    If nothing happens and there is no one around why did it not happen?

    No doudt on the wow....I thought, similar to the announcers, that his throttle stuck since it almost looked like he continued to maintain speed all the way

    The fronts were locked up hard, that doesn't happen when there is no braking available.

    Looking at the last clip of the crash, I believe you can see the front end going down and back up (deceleration - braking and then acceleration) and then he proceeds to go into/through the "wall".

    Those Gen IV engines have DBW throttle control - so it could have been some type of an electrical system failure.

    Here's the in car video:

    throttle didn't stick, you can hear him decelerate, and brakes were locked...i find it most amazing that not only was he okay, but he missed the media personnel that were right there.

    Default listen

    If you watched and listened to the OP's video post O Gavin talked to the driver on the radio and he said the pedal went to the floor and he made attempts to pump. At 160 and a car in front of you, you don't get many pumps..

    Take a closer look at the vid posted by Sik, it sounds like the revs went up after the first brake attempt. I also noticed the data logger recorded -1.1 g's on the first braking attempt, thats pretty close to full braking power. I'm guessing the driver screwed up on the heel/toe (also in too deep) and when he went for the brake pedal a second time it was too late. It could be something with a hung throttle but it seems like the throttle is off after the first attempt at braking.

    wow
    That sequential gearbox does not require heel toe, some guys heel toe but the drivers of that car don't (just got off the phone with one of them to verify as I was typing this..). 1.1 is around 50% of braking. Brakes failed, end of story

    I have to agree with Christy J Rottencrotch, looked like he had at least a bunch of pad knockback. One missed pump and he's probably lost too much real estate to dig himself out of the hole.

    my thought was, something went wrong with the brakes, he started pumping. Then he over applied and was locked up and too late to turn in and obviously had no steering control anyway. I would still put ABS in a race car that allowed it.

    ABS is not allowed on those cars by rule.
    Over applied? I see Fag'Goon does not hold a monopoly on stupid comments.

    The reason why I was saying I like ABS was in that case, where a momentary lack of brakes, resulted in a driver over-reaction and a complete loss of brakes to the tune of going into a wall, not that they should have equipped the car with it. I know the Rolex GT rules well enough.
