Awesome work
There are a few things which I would like to suggest, try to make a car with very realistic size. You can search for the car's accurate length and height in Wikipedia or other car information site.


Overall, you did well!
Keep up the good work!

Some tips:

Use density 50 or more for every part that collides, like gears or wheels or pistons (if you ever make an engine). This improves collisions a LOT

Use restitution 0 on gears, this improves traction on them (as you might have noticed, they're slipping too much)

Look around and see if you can learn some Thyme scripting. It is really simple and gives you the tools for whatever you want to do, from a spawn engine to an automatic gunner drone... it is not a matter of concern whether you use them or not at this point in Algobox, every good ol' "phundamentalist" is gone anyways except for a handful of them

And the car behaves like it is on the moon because it is huge. Use realistic scales, not 1:1 if you want, but close (don't make the car longer than 6 meters)

Also the car needs suspension badly, the wheels are hinged to the chassis! You can make a transmission with a stretched axle. This is not considered scripting. You have to put an axle on two things that you want to connect, then hold ALT and move one of them, and the axle will stretch. Then right-click the axle and go to its Script menu, find hingeConstant, and write

1e-30

there, replacing the NaN. This will make the axle totally elastic (its max force is 1*10^-30 which is almost 0). But you cannot write 0 there!
Then go to its axle menu and put Brake, and write +inf on motor torque.
With this you can make a transmission to connect your wheel to the gearbox, or whatever else. You can add a suspension to the wheel now

We needed someone else like you badly here. Welcome to the Algobox (or whatever's left of it anyways)

One more thing, sometimes axles are wobbly. To fix this you have to go to the Script menu of the axle, find legacyMode, and write 0 instead of 1. This will make the axle a little bit less strong but it will eliminate wobbly axles

2106 is not 2107!
