Are you trying to wreck that engine?

OK, start her up.

All right. Just keep the motor running.

You had a wonderful escape. Someone must have left the motor running.

When we got into the garage... he just sat there with his head on the steering wheel... and the motor still running.

As you can see in the back, those are gears, and there's an engine, there's a motor behind one of those gears, which made all the others gears rotate.

And I thought what it would be like if I didn't switch it off ...just closed the garage door and left him there.
