Paul lived part time in Santa Barbara where I live and he was a good man with a loving, caring, giving spirit and heart.
According to one report I’ve seen, there is some speculation that the car lost fluid (either oil or coolant)and then lost traction in that fluid. While I’m not sure about the Carrera GT, water-cooled 911’s have radiators and an oil cooler in the front end of the car.
A tire failure also sounds like a possibility.
The driver had a competition license and some professional experience as a driver, so in theory he would have known better to speed on the street. But it should also be said that the Carrera GT is known for being very tricky to drive.
