And if you are going to get people who fall outside 107%, it's probably going to be cases like Takuma Sato at Albert Park in 2002, when couldn't set a lap time early in qualifying, and by the time he took to the circuit, it was raining heavily.I think it may as well be there, there is no harm. New teams could come in future and potentially be dangerously slow. 107% is not hard to stay within, so if anyone falls outside of it, I think its fair to disqualify them. But, so far we haven't really had many drivers outside of it on genuine pace.
That's another problem with the 107% rule. Let's say Vettel comes out early in Q1 and sets a fast lap time on a dry track, and then rain begins pouring, and Alonso comes out to do some laps, but it's very wet and he's outside the 107%. Would he get disqualified in that situation?
