I have to consider myself lucky. Knock wood, I have not had a failure that endangered me. I have had breakdowns, but they have been of the variety that did not endanger anyone. I've broken a driveshaft, lost a few clutches, and stuff like that. Oh wait!! Once a mechanic left a rag in the engine compartment and it caught on fire at my first stop. I guess the air got a chance to get to it. That was interesting! I put the fire out though.
