Hrm okay, well not exactly the point I was trying to get at. I'm not looking for a reason as to why it happens, as you said you can fill in the blank with your imagination, but rather I was trying to make a suggestion to give the breakdown a meaningful and more importantly fun purpose. So, what I meant is I don't like the sound of random breakdowns for "no fun reason". The point of a game is to have fun, and simply breaking down, hopping off, repair, then back on just doesn't sound fun.
