In particular in this case there are models of the host's possible behaviour in which you would be an idiot to switch. (The host is trying to keep you from winning the car.)
You've made this statement more than once now, and it completely loses me. Can you demonstrate it? I don't actually see where motivation comes into it; the stipulation is that you have a choice to switch or not switch. That implies that a goat door was opened by the host. (If the prize door was opened by the host, you no longer need choose.) And afaict, that a goat door was opened is enough to give you an advantage if you switch.
