last time f1 was racing without refueling the races got boring to the end as every one was saving fuel to make it to the line.
i am not a big fan of that no refueling rule at all
Tyres can make a big difference (specially if they are crappy) so maybe we will have cars with different pace fighting for position, and that can be only good.
Anyway I agree with you in aero revisions... they should make kind of Indy aero limitations.
