The stopping distance is bollox chief as it depends on the vehicle being driven I'm afraid.
The stopping distance does not totally depend on the vehicle.
Road conditions and driver's ability to react are important factors and anybody who is insane enough to drive at that speed in a built up area can have no mental capability at all.
Then again for somebody who lists his interests as 142mph perhaps the comment is not out of character.
My interests aren't 142mph, what you didn't know was this site started off as a car cruise site called cruisewirral, when the site was converted all the profiles were messed up, I've never changed it.
Stopping distances also depend on the car driven.
The weight of the car, the tyres, does it have abs?, does it have discs or drums? Ect.
At that speed trying to do a quick stop would result in the brakes overheating, they overheat they don't work, so yes, it does depend on the car.
