my entry to: CHALLANGE: BUILD YOUR OWN OFF ROAD VEHICLE

My entry to the challenge.

~^~Left slider - torque tradeoff. Only modifyable when held, otherwise sets to best torque for this track.
~^~Right slider - modifies the speed. Doesnt need to be held.
~^~Arrow - reverse button, hold for reverse. Usefull when the car starts to flip or when the wheel gets stuck in ground.

I made essential modification to your track to make it more fair with a timer - added a limit for 1 tick after laser sensor sparsifier, otherwise i would activate the the timer with one wheel and deactivate with other.
