Rotate While In Motion

I’ve got a car, and I’m using logic bricks to drive it.
To make it more realistic, I’ve used a First Modifier on the KEYBOARD sensor
so it only rotates while accelerating. But after letting go of the accelerator,
the car won’t respond to the rotation.

My question is how would I go about making the car keep rotating until it
comes to a complete stop?

Thanks.

A timer property coul do the job.
As you keep the button pressed assign the property value 0,after you release it will increase automatically.
While the property is in interval 0-3 you can do whatever you want, so it wont stop exactly when you release button.
