If the car tears itself apart bad enough in the crash to catch on fire {remember this is not Hollywood where everything bursts into flame at the slightest provocation}....I'm thinking you have bigger problems than the possibility of the pumps running.

So it all comes down to your perceived personal safety threshold, where do you draw the line...where do you risk it?

Secondly, I've driven my car pretty hard over some questionable roads, including some rather abrupt partial lane deviation bounces and never have experienced the potential "metering plate bounce" scenario as outlined by Porsche. So I'm going to call that "over engineering" and just ignore it completely.

Well said, Mark. And the the earlier post you shared from PorscheMD....I had never read that one before. Had no idea about the prevention circuits for those potentially 282 milliseconds of pump-offage.
