Setting the LAND SPEED RECORD in Poly Bridge 3!? 

Check out my BRAND NEW merch designs at: realcivilengineer.com

Matt: We need a wide wheelbase. Also Matt for the rest of the video: Builds vehicles with the smallest wheelbase possible.

It's amazing you did this entire video without realizing adjusting the weight would stop the wheelies

If you want to revisit this, go for a similar idea to the last 'limo driving on top of wheels', but pick the vehicle with the biggest wheels, high horsepower, and make the prop/bridge driving wheels as small as possible - basically trying to gear up the speed. I can't imagine it going well, but the small wheels will rotate a lot faster than the geared down version here.

Day 60 of asking Matt to play No Mans Sky. 9 days left...

really cool video, loved it!! also 13:13 poly bridge 2 does actually have this feature and is called 'edge bisect' + can be toggled haha

12:35 it just blast itself off the map like in a Smash Bros game complete with the stress meter resetting!

16:40 the back wheel is behaving exactly like the tires on dragsters, so probably not necessarily a bad thing.

Fun fact : the delorian is not a sports car, it's made out of stainless steel making it quite heavy. The infamous 88MPH for a delorian to time travel is impossible, the delorian can't reach 88MPH.

I accidentally stumbled into one of your videos a couple weeks ago, you’ve now become one of my most anticipated RU-vid channels. 👍

Hi Matt, just a comment to thank you for your content and particularly on Polly Bridge. I'm a French student, and you have inspired me to work on bridges and to present these masterpieces of engineering 🤌 in my final oral exam. Hope I will convert my examiners to the bridge religion.

This totally absurd episode has got to be one of my favourites!

Why not make a small wheel, put something a bit slower to prevent lag and bugs, and then create a bigger wheel around it and connect it to the smaller wheel? Physics will do the rest of the work. (bicycles and cars use a similar mechanism to control speed) edit: looking at the video I don't think the game simulates the effect of weight on speed so it might work with minimum speed too another edit after seeing what he did at the end: it would work better with the grip from your last version if you make it bigger and work the same way I described (it will also be more interesting considering that instead of making a car go faster inside another car you will make an actual engine that boosts slow cars with the power of ENGINEering). and another edit after reading some of the comments: I watch your videos mainly for the engineering part, I like seeing how things we would usually learn in school can be applied in everyday life, aka, gaming. That's why my favorite videos are the road simulators (specifically the parts where you recreated some real roads) and the simulators you play. I noticed that most of your community, in the comments at least, don't pay attention to this or just don't talk about it much, but I would love to see more thinking going into these videos, I'm in 10th grade, and if I can make up the idea above I can't imagine what a real engineer would do if he will actually try to make something unique. That's why I'm subscribed after all.

Boosh nailed it! It looked great in slow motion, but when you showed it in normal speed, you could realy see how fast it was going. Obviously the xS in the corner, stands for normal speed. And you were going so fast, that from the perspective of the observer it almost looked like the top of the S had flattened. (So it looked a little like this x5)

actually problem with wheelies is soved by adding more weight as center of mass is usually placed before rear wheel so it will pull rest of vechicle down

Seemed like the spring tires were actually doing great, you just needed to provide lateral structure to them so they wouldnt slip. You tried providing the horizontal structure with steel beams but that doesnt keep the wheel from stretching or shrinking horizontally, that just helps support the weight of the vehicle, which was not an issue to begin with so you did not really fix the problem.

I love your Poly Bridge videos so much (and all the other ones too) that I actually bought PB3 at release and I totally love playing it!

Hi, Mechanical Engineer here. Similar to how a torque-to-speed gear box works, perhaps you should try making a gear-esk shape (with teeth and such), where the vehicle turns a larger gear, which then meshes with and transfers rotation to a much smaller gear. If done right (and due to the game appearing to not account for torque losses with speed increases), it could be possible to get the vehicle going crazy speeds, even with a super slow vehicle.

13:11 that is known as “edge bisect”, and in poly bridge 2, you could toggle it by pressing “B”

I was literally wondering why you didn’t have a “truss me I’m an engineer” shirt yesterday. Only to find out I’m somewhat precognitive today. Now I can finally wear the ultimate engineering pun. Hooray!

I didn't think It was possible to set land speed records on Poly Bridge, but I guess Matt can do them anywhere

Just a thought, flip an entire line of limos upside-down, then put a road on it like a conveyor belt. Then put another limo on top of the conveyor. Should double the speed right? :P

I will always love you're shenanigans but, I'm surprised that you didn't do a train like you did in poly bridge 2. Also Drae beat you on the leader board in MM-06 Cliff Brace lol just thought I'd let you know😂😁. Keep up the shenanigans, they always make my day.

12:33 I have watched these few seconds like a dozen times and I can't stop laughing. 😀

Thanks again for uploading another amazing Poly Bridge vid!

Matt the issue you were running into with spring wheels is the same as when drag racer run into issues with the tires folding on them selfs and bunching up and they run into that issue when the air pressure is too low so the solution to your issues would be to increase the pressure of the springs.

16:24 and here kid was the reaction of the first man when he discover the rotary engine

I love how confidently Matt talks about the “new” features in PB3 despite being completely wrong

love the poly bridge videos matt keep doing them!!

I swear I love RCE and your Poly Bridge videos are my lullaby before I go to sleep

you know you’re a good engineer when you worry about *aerodynamics* in a bridge building game.

You should try attatching the wheels to shocks, not steel. That way it absorbs the bumps and wont bounce as much bounce. Great video!

This Video gave me something, I never knew I needed. Now I want it. More plz

12:34 had me laughing for like ten minutes

12:39 this works because its like gears, try putting a tiny "engine" and a giant wheel

17:29 put limos inside the custom circle and triple them to get the fastest vehicle

Matt you should try Scrap Mechanic! Maybe even Trailmakers, Automation, or Beamng! 😀

Well, at least Matt didn't try to sing in this one. Idea for change in game physics for PB4: each vehicle should be explicitly FWD, RWD, or AWD. That limo, on its own, could have been massively overpowered if it were FWD.

7:26 This looks like the airless tyre that companies have been telling us is "just around the corner" for years now. I think an engineer over on the Overdrive YT channel made a cheap version of that.

I can pixture matt driving down the road, paddy at his side, calling bad drivers 'architects' and every so often saying ," oh look paddy were coming up on a bridge. You know ehat that means. A BRIDGE REVIEW!"

3:00 what is Walter's caravan doing in there I was like : Jessie we need to build bridges Jessie 😅

12:54 Editor Speaking Facts

Bro Matt and speed go together like peanut butter and cream cheese

Matt: "Hello, fellow engineers, and welcome back to Poly Bridge 3..." Me: Sandbox Mode, dammit! 😀

Maybe set the land speed record in Plasma. (To measure speed, velocity is in meters per second)

7 Pg is actually 7,000,000,000,000 kilograms, or 7 billion metric tons. To put that in perspective, an Airbus A380 superjumbo jet has a mass of about 285 metric tons. That would mean that the limo has a mass equivalent to nearly 25 million A380s, the largest and heaviest passenger jet ever built. Heck of a heavy car.

Tire size only effects distance covered per revolution. It's easy to spin small tires but the distance covered is a lot less.

I wonder if decoupling the power transfer and wheels interaction with the road would help. Dunno how though.

Hello! Spinning a smaller inner wheel to the tractors' top speed and then making a larger outer wheel, like the tire you make but bigger, would make the outer wheel spin much faster. Plus, The springs help a lot, so maybe making a thin tire out of springs with a rigid structure will help give traction and rigidity. Look at a bicycle wheel.

Footage of Matt discovering why people do wheelies in drag races 2:23

0:15 sneaky lil strongest shape. I see ya ;-)

12:33 Team Arquirocket's blasting off agaaaaaaaain...!!❇

This is te most fun video i have ever watched from you well done ! Love ur vids btw

you can turn off that bisect thing in the options or set a hotkey to turn it on and off (i suggest B, it's unused)

I timed your final creation (took some effort dues to the changing speeds, and was somewhat inaccurate due to the cuts) and got a time to completion of 24.25 seconds. assuming that the length of the track is the maximum possible (to make the speed as high as reasonable) the final speed works out to be at most 25.73 miles per hour, not the 50,000 as advertised.

12:32 Kerbal Bridge Program 3😂😂

13:10 you can turn that off in the settings. I can't remember what the name is but it's there.

3:08 My bus driver be like:

You need to get a wheel as big as possible on the outside and as small as possible in the inside and then put a car in it. This way the car does travels a short distance to turn the wheel one time around and the outside of the wheel travels the a lot more distance in the same time. This means the outer side travels faster than the car and this way you can travel faster than the car itself. It's kind of a makeshift gear. Have not tried it, partially because i do not own Poly Bridge 3, but from the physics side of view it should theoretically work.

Me, reading the title - "Setting the LAND SPEED RECORD" - Oh, its Trailmakers, yes? "In Poly Bridge 3" - hol up

Hey. Love your new merch (just ordered a thsirt :D)

15:43 editor you unlocked in me a memory 🥺

Drag racing tires are left with less air than their max so they sort of fold and grip the road better and it's freaking ace to see in slow motion

We have a long highway and this jump at the end. Let's try the Delorean! I see what you did there... :)

0:15 Strong shape

2:40 More buff hrsprs means MO PAWA BABEY

" Definitely reached 50,000mph " XD

Hi RCe. you could take a monster truck and scale it up to 200%. The tires of the truck should therefore be larger than your chassis. When the monster truck is moving, the wheels on your undercarriage will spin slightly faster than the truck's wheels. Is similar to the gearbox, the smaller the last gear, the faster the vehicle.

Reid Captain builds a working bike, impressive… Matt tries to build a car…whooosh

I don't think Matt has seen slow-mo videos of drag cars starting. The drive wheels are twisted so hard they almost collapse, giving them a lot more surface area on the track and, as a result, a lot more traction.

It is gonna be hard to break RCE's totally legitimate 50000 km/hr land speed record

Love the poly content

"I recommend DeLorean will be pretty fast" Every person who sees a DeLorean and isn't familiar with their power train. 😂👍

Whatever bug occurred to fling the vehicle into space, use that same bug but learn how to steer it.

Honey wake up, Real civil engineer uploaded a new video!

No Man's Sky has bridges... y'all should look into that, Matt and team.

Matt making Bridges and trying to break speed records 😅😂 We all how this one is gonna turn out 😂

9:45 it looks like a bike with no seat! Haha

So the plan to make the limo go faster was to have the limo’s small wheels drive some bigger wheels effectively working like a small gear driving a larger gear. Not sure why that didn’t work, I think the game is broken 😂

How is this game calculating/simulating speed and acceleration since they are independent from horsepower

"OMG It's so small, Its sOoO small, but yeah let's shove that at the very start" ... not the first time i've heard that ;)

Matt: “i reckon the delorean will be fast” Me, a car guy: 🤦‍♂️

Gear ratios would suggest that if your wheel is larger then the limo wheel it will be slower, how small can you make a working wheel

The desert rally is one of the fastest cars in PB3

I like how you accidentally basically recreated how tanks were invented, which was putting stuff on a tractor lol

I like the joke of the dorlorin being fast ha...ha...wait he was serious?

10:26 “the wheel, well, our wheel” *Soviet anthem intensifies*

The monster flipper would be really good at making a conveyor belt ngl

10:39 BACKFLIP

15:43 man that takes me back some

It would be really cool if you made a roller coaster in polly bridge

3:18 my favorite part

The Delorian in this game looks like what would you would get if you crossed a Delorian with a 1980 Dodge Omni.

LMAO the editor commentary is GREAT!

you not realizing that making the cars heavier would stop the wheelies infuriated me

Matt and gear ratios is the new Matt and hydraulics.

50,0000! Good god Matt, you’ve done it again my boy!

Fast and Furious

Poly Bridge 2 had that option too. Or at least it has now (mabye patched in). 13:15
