I don't have a problem with having 1 tyre manufacturer. Don't really want a repeat of 2005 where Michelin completely dominated Bridgestone, except in the USA of course
I think they need to bring back refuelling but also lift the bullshit rev limiter and engine/gearbox usage rule. They already have an engine development freeze to cut costs, so imo it should be a free for all in regards to tuning these things for max hp. Might see a few blowing them up (insert a certain drivers name in here), but that's just a part of racing.
