Single tyre manufacturers aren't always good. They are best for club series where money is an issue and everyone needs to be on standardised equipment; I'm not sure it's best for world championships. In a way I kind of admire Michelin for quitting F1 as they see no reason to be competing if there is no competition. MotoGP has 3 different tyre manufacturers and the racing is fantastic there, and this is a series that has no aerodynamic grip and so rely totally on tyres for speed.
The best F1 cars would be 1970 beasts returning with improved safety. And as stated earlier, carbon brakes are simply not needed anymore with modern F1 cars. They keep them because F1 has to be "high tech". I like high tech, but I don't like Fernando Alonso being penalised @ Monza by a politician because the data supplied showed aerodynamic grip loss through one corner, despite the said driver being about 100m behind. Most fans don't give a monkeys about aerodynamic data, they want racing. There's a technology element in F1 and a human element. There's too much technology at the moment.
Hmm....that turned into a mini-rant
Don't worry FreQ, It's hard not to rant when talking about F1 these days.
At least we should get a good championship next year with all of the driver changes, Hopefully Raikonen will have a car capable of winning, McLaren will give Alonso and Hamilton a reliable car and Renault keep up their consistency and speed they have had over the last few years.
