I wonder how many deaths are attributed to auto boxes alone....?
A little old and perhaps tenuious but back in the 80's there was a case of a mercades lorry pulling a tanker of petrol or oil which crashed in a town in Germany. It's brakes had failed and the auto (or semi auto , I forget)box wouldn't let the driver select a lower gear to slow down or stop the vehical as a lower gear would have speed the engine up too much.I'm unsure as to if there were any fatalities though. I've tried googling but haven't come up with the incident but do remember reading it in Truck magazine.
As I say it was back in the 80's and auto boxes have got a lot better.
