Even with more skill I think it would’ve been tough for the gixxer to make it around the car. At the 2:12 mark it looks like the gixxer had some extra space on the right side that he could’ve used, but they were on a left hand curve so he would’ve had to drift out toward the outside of the turn… which is ballsy at that speed because it would’ve been hard to get the bike back on line after you go around the merecedes, so he probably would’ve gone off the road into the trees anyway.
The R1 could’ve easily released the brakes and gone around the back of the car. He probably froze and target fixated on the car, and once he was on the brakes he was committed to braking until he stopped or until he hit the car.
