The problem might be the behavior of car (behavior)
Car behavior is not flexible then rotate-to (set angle), and it seems that car could not rotate if it can not move forward. It means that you might turn left/right early.
You might see my racing car sample capx in 1st post of this thread.
Is it possible to approximate it? It doesn't really break much, and gets back up to speed fairly fast. Unless the bullet can be made a bit less "fluttery"?
