wheel colliders on mesh colliders

Questions & Answers
1

If wheel colliders sink through mesh colliders, then how are driving games made with Unity? I know that ticking the Convex check-box will solve this problem, but then the custom-made map will look entirely differently. What I mean is a map with hills, not a flat map. A map made in modelling software, not in Unity.

It is practically impossible to place 10000 box colliders to act like a mesh collider. Ticking the Convex check-box is going to mess up the map. So what is the workaround with this? Is there one?

To make my question clearer: How can I get wheel colliders to detect mesh colliders while the convex check-box is not checked? If that’s not possible, then is there another method to have my wheels spinning (and moving my car) and be physically realistic?

If your wheel colliders have a radius of something like 1 they won’t work very well because they’re too small. Or, your rigidbody could be too heavy. But, I don’t know; wheel colliders are strange.
