Collsion

Hi!

How can I increase the collision accuracy?
In the image you can see, that i can drive into the bar, only when i drive a little further the wheel jumps on the bar- I tried bounding boxes with margins in physics and material.. nothing helps.

And when i am fast enough, im driving right through the bars.

Bullet's vehicle implementation uses ray casting so perpendicular surfaces as in your case produce such incorrect behaviour. You can fix that by using additional invisible sloped surfaces.
