Yep. That was the main point on my edit. The OP is asking how is it possible, when the engine becomes overheated, to automatically destroy the car. The radio is just noise in the question.
Also, you removed the fact that the OP wants to start the radio when the engine starts, and turned it into just that the car needs to be destroyed when over a certain temp.
Actually, they want to do someone to the radio, so it's not just noise.
@Undo: Ok. I still, as a strictly personal opinion, think it isn't a really good option (I think fixing irrelevant issues in the code is as usefull as grammar mistake), but if it is what the community agrees on, I won't do it anymore, for sure.
