Yes, there is plenty of brilliant technical innovations going on in Formula 1. The passive DRS that Lotus has experimenting with or the way the Red Bull uses a special material on the side skirts that bends when heated up by the exhaust air to improve downforce. Limitations is a great fuel for innovation. There is not very much going on in terms of engines in Formula 1 at the moment, but in aerodynamics it is still amazing what they are achieving.
I don't think tyre strategy is all that interesting. To me Webber hopping Massa was far last interesting than Hamiltons duel with Raikkonen.
I agree. Maybe the only real limitation should be how much a team can spend per year, a 'team cap'.
Not true at all. If the cars were practically identical Red Bull wouldn't be running away with the championship every year. As important as the drivers are in F1 the car is much more important.
>> "Formula 1 was ruined by restrictions on maximal engine performance, acceleration... even tyres are dictated"
Without some of those restrictions most of the smaller teams couldn't afford to go racing. We would lose probably half the teams. And tyres are what has made F1 so exciting these last few years. Tyres could easily be made to last an entire race taking away the strategy aspect from F1 that makes it so interesting.
