Title: Automatically turn engines on and off when appropriate.

When driving, the "turn engine off" option becomes "stop driving", which lets go of the controls as well as turning it off.

The "let go" option is still there for if you want to leave it running.

Also, when first taking control, the engine is automatically started.
