you have to turn the engines off once you're onboard. which is why as soon as I boarded I left my car and went for the upstairs passenger lounge. Looking down below is when I noticed all the obeasts that couldn't get out of their vehicles and had to sit in the sweltering heat. I think if there is anything in this world that would motivate me to lose weight it would be being stuck in a hot car because I can't squeeze my body out of the door.
