With all due respect to the deceased, they must have been racing, because I cannot think of any car that can suddenly go out of control in the hands of a skilled driver that would turn their car into something that looks like it came from a wrecker’s yard.
Note also the sign for a 15 mph curve ahead, and if you back out of street view you can see the corner. I would suppose the driver was seduced by the sweeping curve and was showing off his acceleration, then got surprised by what amounts to a dead end. Probably was not going hyper-fast, maybe only 60 or 70 mph, but braked too hard and spun out.
Paul lived part time in Santa Barbara where I live and he was a good man with a loving, caring, giving spirit and heart.
