Are their A pillars really that weak?

Looks like the entry to "the b1tch" turn at Hallett, he must have lost it going up the hill at T7-8. I went off at the same place at the last PCA race.

He's lucky to be alive, wondering if he was wearing a HANS device. Yet another reason to race a lightweight car, less stuff to crush you with when it goes over.

I have seen both BMW's & Porsches that have had the roofs crushed like that at Mosport.That pivot over on to the roof made for a very heavy impact but a car with a properly welded in cage would have handled a crash like that much better than a cage that penatrated the floor.

Wow, glad he made it out OK.

Amazing the driver got out of that relatively unscathed - judging where he ended up, must have been caring a lot of speed to go through the tires and end upside down! Wonder what would have happened if there was no cage at all?

Don't confuse roll cage and roll bar. This was a bar and it was installed by idiots. This bar didn't offer any resistance at all, as it went straight through the underside of the car. The effect would have been the same, had the bar not been there. Normally you weld steel plates to a cars chassis before mounting bolt in bars or cages. These plates are there to insure that the forces created by an impact are spread out instead of putting pressure on just a very small area, thus just punching a hole in the cars floor. If things are done right, there is no difference between "screw" and "weld", e.g. if both are done according to FIA standards. To me the tire "barrier" and the catch fencing is very interesting too.

Thanks - no i wasnt confusing the two, just a typo! Figure the floor might have offered a little resistance though.

Glad the guy was Ok!
