i believe the shaking is a camera switch triggered by speed that is failed to recognize slowing down fast. leaving it thinking "high speed" while sitting

awesome effects though
eventually we need to find out a pure transmission system with gears, power to rpm, and max on certain gear. (i get multiple gears in reverse, and odd sound shifting when spinning)

when I want the camera shake intensity to change at different speeds I like to modify the vehicle dust script to have the shake intensity increase when the car goes faster.
