Last year,had tuned reactor car method.It had a bad point for steering.As you see,I've override the past method.This car use many expressions,constraints&reactor helpers.but,you can see
many tire bad collisions(overdo read n repulse the terrain ruggdeness).because of,car have a light mass.In the remote I can set balance n tire contraction by physical force.I have a long way to go.3dsmax powered.
