Short answer - probably.

You've obviously expeienced one of my flights.................. =))

Work out how many crashes result in survivable events and do the sums. Everything in all life is balanced on risk.

Barényi is also credited with first conceiving the original design for the German people's car (the Volkswagen Beetle) in 1925, – notably by Mercedes-Benz, on their website, including his original technical drawing, – five years before Ferdinand Porsche claimed to have made his initial version.
Even the slightest rear-end dink into a Beetle by any ordinary car of normal front-bumper height, would bugger the starter motor and the alternator.

I experienced that twice, as a bumpee, within three weeks in Nigeria when Beetles ("Built in Nigeria for Nigerian roads") were standard issue by the Nigerio-British-European oil company for whom I worked at the time. I sent a stinker of an internal memo and was gifted a Peugot 504 (or was it a 405?) as compensation for my troubles.

Mebbe Herr Barényi's notion was that an alternator/motor was a suitable rear crumple zone to protect one's arsche.

The story of the VW is very interesting.

My grandfather, who worked for GM in SA, knew Ganz through his trips to Australia.

The very first time I drove a car, an Opel Kadett, I contrived to dent a VW, driven by a German from South West Africa whose father had been a ME 109 pilot. After a rocky start (I had dented his pride and joy after all) we became friends...I think he forgave me because I was driving a German designed car.
