This was not a freak accident, it is entirely predictable. You only have to look at the possibilities of a car going end over end and you can clearly see where a car will land. It is bleeding obvious to anyone that looks hard enough but the CAMS track inspectors seem to miss the obvious.


May as well close all the tracks to spectators and only have the film crews there then

How about not placing the spectators in a direct line of the cars when they are out of control or build the fences so that they will stop a car before it enters the crowd.
It is not that hard to do but it seems to get ignored.

nearly happened again today.. i had an abs fail safe misshap but used dean canto to stop me instead of the crowd.. :oops: and another car was involved in a huge accident where, i believe the abs went into fail safe again causing her to drive off the track at turn 6 at about 150kmh and hit the wall at about 100, nearly launching it into the crowd again... driver was ok but car wasnt..

just to clarify, the abs system in these cars works like on your road car, in a situation when the wheels would be locking up the pedal kicks back at you and it self limits the aplication, now we have similar size brakes to v8 supercars so you can imagine how well the brakes want to work, under hard braking you can feel it kicking in and out but on some occaisions, they become over stressed and go into whats called fail safe, or override mode.. which makes the pedal go rock hard (literally) and the brakes not work at all... (literally) this continues for about 2 seconds while the computer thinks about whats happening.. which, in a race car braking from 80 meters from 200 kmh is far too much time, by the time its working again, youve hit something/ someone. i want this system reviewed after this weekend... its causing far too much damage worldwide.

i think the crazy and rediculous bumps of queensland raceway amplified a problem which has been around for some time.. but thats just my opinion..

:shock: :shock: :shock:

I'd be getting all the other drivers to join you on a strike or something to get that fixed before you go anywhere near a racetrack again!! someone is going to die

Correct me if im wrong, But arent the bumps at the end of the back straight caused by the v8s? The mass of the cars and the size of the brakes physically rippling the bitumen into bumps?

this is interesting, under hard braking on turn 3 my stereo turns off ! no idea why. makes it hard to put in a good lap time in when u have to restart the radio.

Why do they have abs in racing? Once you hit the kitty litter the
brakes fail to work completely or if two wheels are off the edge they also fail to work.
Ok the kitty litter is meant to slow you down but you would slow a damn
lot quicker if you could lock your brakes.
The skill in racing should be in the drivers ability with the brakes, but it
sounds like they work against you.

the challenge cars are over braked.. they lock up all the time when you dont have the abs on.. that said, id rather be able to lock the brakes and ease out of the pedal to bring it under control then have that free wheeling "i cant do anything about this car" feeling.. some people said to me over the weekend that locking brakes would give the same effect.. thats untrue as there is at least some sort of resistance from the friction of the rubber against the tarmac when locked..

my damage bill form the weekend will be something like 5 grand which was a couple of suspension bits and a rim.. id rather spend half that on new tyres when i flat spot them and finish a race..

if you want to know what it feels like when this happens get up to 200 kmh then just take your feet off the pedals :wink:
