Cool stuff! I am planning to do a tutorial for a vehicle myself so wanted to check this out. (Perhaps a bit more higher poly and will include a quick fun way to make tires without using the dreaded cylinder!) If you press G and then an axis shortcut key such as Y,X or Z then simply move the object you can move it on an axis at a certain distance. (If you observe the left upper part of your screen, you'll see the distance in meters as you move it.) So then if you google how many meters is a bus for example, you'll know exactly how much distance you'll need and can use a streched out cube as a distance marker where needed. While it may seem like chaotic movement numbers in that top left corner you can be more exact and move by meters with snapping mode on. Simply press the horeshoe icon (magnet) at the top and set the dropdown next to it to "increment" . Each default cube is 2x2m (meters) and if you duplicate the default cube and move it two meters over it will be exactly next to the other. Alternative to having snapping mode on, you can still move the object in increments (meters) by default just by holding down ctrl when you move an object freely or along an axis as mentioned above. But with snapping mode and increments selected in the dropdown it's nice to be able to move in meters just by moving the object and if you hold shift with snapping on you can even move in centimeters and once again you can see the exact result of your movements in the top left as a guide. If you press "S" you can of course scale objects on an axis then enter the number you want to scale based on your needs or of course just enter the numbers in the scale portion of your object properties tab. Hope this helps your blender journey or makes it easier for you in some way and I am loving the idea of public transportation. A lot of strange or interesting things can happen on the subway or bus sometimes that may lead to some fun game moments. btw I noticed you didn't verbally say "Make an inset" when you made the front and the back windows. I know it's easy to forget to mention what you're doing so that's why I think having your keys displayed as an addon makes tutorials a bit easier to follow sometimes.
Oh before I forget at 26:40 you said there may be a better way to grab the windows. I was stumped for a minute...but just click a face, then hold crtl and hit plus on the numb pad. Then shift left mouse button click on the face to deselect it and you'll have just the inset selected.
This is the best tutorial I've ever seen in my entire life. It felt like you were embarking on a new adventure and you were taking me with you to explore the seas and to make a bus in blender. I can't wait to go on another adventure with my new best friend ❤🩹❤🩹🤩🤩🤗🤗
