car wheels whitout a script

Hello i am making something but encounter the following problem.

Example:if you got a car.You want it to move when you let the wheels turn using the keyboard,but when you stop pressing that key you want it to stop.So when the car climbs a hill it doesnt roll down hill when stop pressing the forward key.

I cant achieve this,maby someone can help me.

Hmmm…a logic brick solution would probably be to use a touch sensor with the property “hill”, or something like that, and then add a motion actuator that applies a certain force to it when its touching a hill.

You need a script? Here is a tutorial:
