GOOD NEWS, EVERYONE! Consumer reports picked up on this video and did testing which confirmed that this issue affects nearly all Hyundai/Kia E-GMP platform cars (and I very much appreciate them giving a shoutout to this video!) www.consumerreports.org/cars/car-safety/brake-lights-can-fail-to-provide-fair-warning-on-some-evs-a9533519285/ And now! Hyundai will fix this. They're calling it a "field service campaign" and it will begin in July. Weirdly, Kia hasn't said anything yet at the time of this comment's posting. www.autoblog.com/2023/06/15/kia-hyundai-genesis-one-pedal-braking/ Now, while I'm glad Hyundai is doing the right thing (and hopefully Kia does soon), I believe we still very much need a clear, unambiguous regulation to unify brake light behavior with features like one-pedal driving. We are still leaving too much up to manufacturers right now.

Could you do a video highlighting the car's charging issues next? There's widespread issues with Level 2 charging on the Ioniq 5 when charging at higher amperages (typically over 32 amps). The service campaign they released to address the issue simply throttles charging down to unacceptably low speeds. Doesn't seem like Hyundai cares enough to issue a recall.

@SirBlastalot 11 месяцев назад

If you're at one of the manufacturers that does this, could you ask the team to stop doing the thing where brakelights FLASH every time you press the brake? It bothers me when I see it, because flashing your brakes already means "back off," and sending that message every time you brake is like leaning on your horn every time you have the car in gear; it just leads to alert fatigue and reduces your ability to actually communicate with the drivers around you.

Also turning on reverse (white) lights when unlocking a car needs to stop. This makes it appear as if a car is about to back up, but it's just being unlocked in a dark environment. It adds alert fatigue which means when someone really is backing up, you might think they're just getting in the cars. I think Chevrolet does this and it drives me nuts.

@Jack_Stafford 5 месяцев назад

At one point about 20 years ago, there were talks of regs that would have had at least two stages of lights, one for braking, and another brighter light for HEAVY BRAKING, or lights that progressively got brighter the heavier they were used, so drivers would know if someone was merely slowing down or slamming on the brakes to avoid an obstacle. It didn't go anywhere in the government, but something that definitely should be revisited.

@Beany87 3 месяца назад

I NEED this! So much congestion on motorways (at least in the UK) is caused by ''they braked so I'll brake''. If someones brake lights are out is the cause of you crashing into them, frankly, you should not be driving!

@timlong1462 2 месяца назад

I've always wanted an "accelerator off" pedal, and progressing lights. There was actually a question on the license test I took 18 years ago. The question was "what is the purpose of the 3rd upper light on the rear of a car?" One of the incorrect multiple choices was "accelerator off light". That stuck with me and I've always thought it's a great idea to add. Combine that with the new style fancy multi bar brake lights like in the thumbnail, you could make them ramp in how many bars are lit, then rose in intensity if it's slamming on the brakes.

It’s not that engineers are lazy. It’s that manufactures are cheap. They can save an extra bulb and wiring. Easy money. As far as the software bmw already had this software designed into there cruise control. If it was slowing itself down it would illuminate the brakes if you were slowing down faster than some meters per second rate. This was back in 2008 as that’s what’s in my cars owners manual. People always say the Germans over engineer but they seem to actually think about the important things like brake lights. They also have a multi state brake light system so if your stomping on the brakes it illuminates a second set of lightbulbs, giving you more advanced notice as the driver behind them. They also flash your third brake light when you slam on your brakes and activate ABS. This multi stage braking system should be standard across the board for all manufactures.

This brake light problem was one of the first things I noticed out on the road as I learned to drive. I live in an area with a high concentration of electric vehicles. It bothered me that some of these vehicles could be slowly down so rapidly without any light indicator. I remember speaking with my father about it on many of my practice drives preparing for my test. Vehicles should have some software to activate the light if they are decelerating at a certain rate, even if the driver is not engaging the brake pedal.

@justinmaxon12 3 месяца назад

The requirements (at least in the USA) are not based on energy use, they are based on Lumen output. Lumens are an antiquated measurement based on the light output of candles, which have a lot of red light. LED's on the other hand typically have very little red light. So what was originally a law to limit the light output of vehicles to avoid them blinding other drivers, ended up being skirted by using light that doesn't read anywhere near as high in lumens while being far brighter.

I believe this has to do with the car's back door. In Europe,turn signals must be visible at all times whether the back door is open or closed. Which means that if the door opens sideways, you can't have the indicators right next to them. You want the hazard lights to be completely visible when your car is standing at the hard shoulder of the motorway, even while you are grabbing the spare wheel from the (open) trunk. As a result, the European versions of quite a few cars have their turn signals (and tail lights) moved below the door, and only the brake lights where their American counterparts would also have the turn signals and the tail lights.

This Silverado has the exact thing you mentioned where the brake light was implemented with the turn signals, and because he was tapping his brakes while simultaneously using his turn signal I got confused and ended up getting in an accident over it. I highly agree with making it a law that turn signals are to to be amber and separate from the brake lights.

The accelerometer approach for the Bolt is actually a pretty decent idea since it's a hardware double check to the software's logic on pedal position. It's a redundant system, which, when talking about a safety item, is a good thing. Also, manual drivers are plenty used to not always having brake lights illuminated at traffic lights considering we can leave the car in neutral on a flat surface and not have to hold any pedals.

I know it’s difficult putting in an entirely new lighting regulation in place, but if you think about the hybrid formula 1 cars, they don’t have brake lights at all, but they do have red lights on the rear. They actually flash a few times when the vehicle is going charging the battery, or “harvesting” it’s meant to tell a driver behind that they’re going slowly. Flashing red lights could be confusing in this country, so maybe using a light in the back that’s a different color? Maybe green since that’s the only color that isn’t close to red or yellow, and you don’t want blue because that could cause confusion with emergency vehicles. I think it’s a pretty good idea.

I think the brake light NEEDS to be accelerometer based, (or based on using the speedometer and calculating rate of declaration) because if you used the regen alone, it might turn your brake light on even when going a constant speed (down a hill, for example. you don't want your brake light coming on if you are maintaining the speed limit but still getting significant regen).

@TechnologyConnections 11 месяцев назад

@@didikohen455 Oh, they shouldn't, but they do.

@YorikSar 11 месяцев назад

I think it's quite the opposite. The brake light SHOULD NEVER turn on when vehicle decelerates without intent by human or computer. I.e. when it's hitting the wall, there should be no lights. When you go downhill on ICE car, you (or cruise control) apply brakes and they light up the brake signal. It means that you're (or computer is) fighting against gravity, and it's good to know to me who follows you and intuits that braking on this slope is a good idea, maybe we both should do that. If your light doesn't come on, I would think that you're probably ok with going faster, because if you don't brake down the slope, you go faster. Overall lights show intent, not the actual result. Turn signals turn on when you (or your computer, maybe) is about to turn, not when your car pans right when road turns; reverse signal turns on when your switch to reverse "gear", not when you forget to pull handbrake and stepped out of the car. Just like those, brake lights should not turn on when car goes uphill, hits rough patch or decelerates, only when someone (human or otherwise) intentionally slows it down (or tries at least).

@wittyman37 11 месяцев назад

Yeah I agree that brake lights should signal intent and not what is happening. With a manual transmission ICE car it has been possible to slow down very quickly by downshifting for decades (and probably since we started adding multiple gears to cars) but I don't think any manual car turns on the brake lights when the transmission is slowing the car down.

@stevestojan 4 месяца назад

Do you have any concern that in a crash scenario your instinct to slam on the break pedal would be decreased due to no longer using it in order to break? That's what my concern is, as in emergency scenarios you rely on instinct, so no longer using the break pedal to stop could cause you to lose that association and thus lose the instinct that pressing the break pedal is what you do to stop. I'm interested if there is any data tracking how many crashes occurred where the driver failed to press the break pedal, and whether the driver was using one pedal driving, because I have a theory that one pedal driving will increase the number or crashes where the break pedal isn't pressed.

I wouldn't worry too much, most new cars have electronic parking brakes and an electric motor onto the caliper for adaptive cruise control and emergency brake assist.

Honestly most EV's with one pedal drive don't have this brake light issue that much. Ironically in my experience driving for a job, the tesla's are bad at this brake light issue, though it's not consistent with everyone, but not everyone uses one pedal drive.

@emptywindexbottle97 5 месяцев назад

I don't know about the rest of the world but in sweden we have something called the three second rule. You learn that you should have three seconds of travel distance between you and the car in front, measured by starting to count when the car in front passes a pole or sign and stopping the count when your front end has passed that same point. It's very smart in my opinion as it not only let's you know how much distance you need to be safe but the distance also increses when speeds increse, as it should.

@@emptywindexbottle97 that’s a good mentality but I take it one step further. Since speed is variable, so should the safe distance.

@WhoStoleMyAlias 3 месяца назад

Yes except as the guy says the brake lights will already come on when you take your take your foot of the "accelerator" pedal completely. And the bad thing about that is of course that this will also make you decelerate even more. So no, this whole one pedal driving concept is not well thought about at all and should be banned and regenerative braking should also only occur when there is an actual intent of braking, not when traffic in front of you gradually slows down or when entering an area that has a lower speed limit. Further more we should start teaching people how to be responsible drivers again, because to me it is amazing to see people drive around while apparently not even knowing where the light switch is located as they ignore traffic signs that state you need to turn the lights on.

Just don't make like GM and forget the mechanism to leave the light on when stopped :p

Motorcycles have a similar issue. I rarely use my brakes except for the final 10mph or so before stopping because the engine braking is so strong. I have to consciously drag the rear brake when slowing down to warn traffic behind me. The do sell aftermarket brake light kits that use some sort of accelerometer to detect when slowing is occurring to somewhat automate the brake light.

@christianfidanza6712 28 дней назад

I’m a diesel technician. Diesel highway tractors (or semi-trucks) have what’s called an engine brake. In laymen’s terms, it’s essentially a variable valve timing system that slows the engine down. When these engine brakes are engaged, the truck will decelerate similar to that of a moderate brake application. Since I can remember, commencement of the engine brakes would trigger the brake lights on all make or models. 😊

@randomthingswithwheels1641 11 месяцев назад

As someone who drives a manual, the deceleration at low gear is quite noticable and I'm always weary of someone not paying attention. So I always dab the brakes even though I don't need to. Just wishing that whoever is writing the regulations doesn't forget about the good old manuals.

Agreed. Less than a minute into the video 0:50 and he says "The brakes are the only thing capable of slowing the vehicle down enough to warrant turning on the brake lights", I was shocked. Usually so scrupulous, how could he overlook manual transmission cars with more engine braking? Not every manual is a low-displacement, low compression econobox incapable of appreciable slowing under engine braking alone. And certainly the behavior of the vehicle when lifting off the throttle is dramatically different for those vehicles than for almost every automatic.

@xavemsk88 2 месяца назад

Somebody here already wrote about downshifting on mt cars. I drive one and have to say there are not many situations where braking with intensive shifting down is useful. Usually engine braking is used to get a constant speed on downhills w/o heating a convient brakes. But on motorcycles an accelerator design is allowed to control speed of throttle opening only but closing too. (A reverse moving of car pedal is limited by spring force). So this makes downshift braking much easier and faster and when I ride, I almost don't use friction brakes.

Here is my idea to the AutoMakers. Electric cars with one-pedal driving can be confusing for drivers behind them because the brake lights only come on when the driver steps on the brake pedal. To fix this, carmakers could add new lights! Here's the idea: Keep the red brake lights for when the driver hits the brakes. Add 1 or 2 yellow/orange lights in the middle of the back. If using 2 yellow/orrange lights One can be in the top center and the other one can be in the middle or bottom Center. These new lights would turn on whenever the car slows down a lot, even if the driver isn't using the brake pedal (like when they're letting off the gas in one-pedal mode or when a sencor senses a retreat [with the indicated Centimeter minimum] in the Gas pedal). This way, drivers behind electric cars will always know when they're slowing down, no matter how the driver is doing it. Yellow/Orange lights: The Car is Cruising but is slowing down. Red Light: Breaks applied.

Fantastic video - I was quite surprised to see that the Ioniq's brake light didn't come on when the G-force approached -0.3G! However, I noticed that you didn't touch on the blended brake control feature that's integral to the one-pedal driving system, hyundai referred to as 'i-pedal.' This feature explains why manual regenerative braking doesn't bring the car to a complete halt. Having driven the Ioniq myself, I must admit I'm not a fan of the shifter's regen settings.

The difference here is that a motorcycle has two brakes and you're almost always easily able to use one of them and the brake light switch can easily be activated without doing any actual braking.

Any time I've been on a motorcycle and using engine braking it's never been an annoyance to simply slightly squeeze the brake lever to light up the brake lights.

I thought it was very good, because it really makes a difference for the person behind me when they see me breaking regularly, to a hard break it shows a dramatic high intense light which definitely catches their attention and makes them aware that the breaking is being done way harder.

Lighting up is permitted if the delay is more than 0.7 m/s² and mandatory if the delay is more than 1.3 m/s².
