Cars moving through walls

It seems like this happens every time I have a new class. Why, in this game CoSpaces Edu :: 6/7 Video Game Design, August 2021 are the cars driving through walls? They have applied physics to control the cars.

Also, in the same game, why are the 3D cars they have downloaded always driving backwards, no matter how we code them?!

You didn’t apply physics to the car and the wall. Recheck your code.
I’ve applied physics in this remix

The one problem is that cospaces physics are a little unreliable.
