Talkiet:Jase2985:the driver in front cant be at fault, period. it doesnt matter what they do, the rear driver must be able to stop in half the traveling distance. its called failing to stop short.
With no exceptions? Oh, ok.

Your brake check examples show cars pulling in front of another vehicle inside what would be a safe following distance. In normal circumstances the overtaken vehicle should drop back to a safe distance. At anything over 50km/h there is a rule that you have to leave enough following distance to allow for overtaking.
As for performance cars I wouldn't be surprised if at slow speeds your average shopping cart's brakes weren't more effective. Brakes designed for high speeds often need to be bought up to operating temperature.
