By the way, he wasn't "RACING" his car. It was a parade lap. Although you can imagine, from the journalistic point of view, it sucks to print "he crashed his Carrera GT on a parade lap".
Granted, he was doing 165mph on a parade lap ... which he wasn't supposed to be doing. Sigh. I feel sorry for his family, and the passenger, and the passenger's family.
