Well I look at the first video and then the second ZR1 video, I am led to a conclusion.
It's not a good idea to use all that HP to bust the back tires loose at speed. (2nd vid)
Nor is it a good idea to use all that HP to attempt to massively accelerate out of a corner before getting to the apex. (1st vid)
It also looked like the guy lost the back wheels and didn't try to turn into the slide which is why his nose went straight into the 300c.
