A.i indestructable

Why is it when I put damage to sim … and I even purposly rqm cars head on just to test my theory … my while car shuts diwn with damage but the A.U just put ut in reverse and just drive away blno problem.
I they pile up at ever tiny corner with no concequence … and they drive so stubborn … they’d rather take two or three cars in to a wall instead of just braking or turning …u know … into the turn …
FIX THIS !!!
