Hmmm. By the Google map scale ( and using a ruler, folks ) I get 580 ft to the sharp corner, so if he was doing 100 ft/sec ( about 70 mph ) he would have required a deceleration of 8.6 ft/sec2 for about 11 seconds to come to a stop at the corner, which seems an easy requirement.
Maybe he was going a lot faster, or maybe the 15mph corner had nothing to do with the crash, and he just spun out coming out of the sweeping curve. Note the crash site is on the inside of the curve, just past the start of the straightaway, so he didn’t just skid out of the turn.
Porsche Carrera GT most dangerous car in the world.
