Rules the same except they let drivers crash eachother out in the races more without consequences. That overtaking is harder then ever seems proven actually but cars is faster and maybe longer tife span can get the pit overtaking more interesting? In the future I expect more undercuts then overcuts though seeing how easy it is to keep a faster driver behind. Cars look cooler with thicker tires but to bad about the shark fin. And there is to much pink in the force india car.
