Unreal Engine - Arcade car physics
Tried to figure out how to do something like this in Unreal, have done something similar in Unity before.
The idea is to have a simple rigid body, like a box, and then do raycasts where the wheels are. Then add force depending on the length of the raycast. So they act kinda like springs. I toggle on the debug mode sometimes, so you can see a bit more what is going on.
