Some more MaxScript fun 
This is going to be a rigged car ( with inertia, tire pressure based on gravity / inertia ) that will be drivable real-time in a viewport via MaxScript
( The car will also leave tracks when turning at high speed or when doing a burnout start
the RPM and Speedometer will also be real-time functional :))
I might as well add some ‘’ Real-time weapon change ‘’ … just kiddin

Next Step : Tire pressure base on car weight / inertia + tweaks on inertia behavior
