Oh, and Ardius, why do you like city circuits? I dislike them mainly for two reasons: a) 90º corners; b) apart from the cars all you see is concrete walls and fences.
I quite liked the few US ones because they were rapid, and very extreme on reliability and endurance. The poor maintenance of the US street circuits also provided loads of bumps and uneven surfaces, which is in my opinion the best recipe for a good race track.
They pretty much summed up F1 to me.
I don't see why you think they were all 90 degree corners though, only Phoenix was like that, Dallas, Detroit and Long Beach were all great circuits.
Can't argue with the concrete walls comment, and of course I wouldn't like to see an entire season of street circuits. But I do think they have a place in F1 and I feel Valencia and Singapore just don't do the name "street circuit" justice.
Melbourne and Montreal are technically street circuits and feature many of the charateristics of street circuits. The origins of racing were on streets too, the greatest race circuits in the world are mostly built on old roadways.
Of course, overtaking was difficult, but not impossible. Watson at Long Beach 1983? Senna and Alesi at Phoneix 1990?
Full blown race circuits can be good with their freedom, but they can be a bit too perfect with their surfaces and acres of run off. Especially nowadays when we get places like Abu Dhabi. Its a bit silly how we still have circuits like Suzuka which still use grass and gravel (so its clearly not such a safety problem) yet all the new circuits are choosing to use tarmac run offs. I can only agree with tarmac run offs with respect to bikers, but otherwise I would rather see cars taken out and punished for mistakes rather than have effectively car parks. Not only does it look grey and dull, but it doesn't provide any better racing anyway.
Its a controversial question, but does anyone else think tarmac run off is a safety feature we don't need? The excitement is generated from the element of danger and I wonder whether tarmac is absolutely necessary. The main argument for tarmac run off is to help safety, as its easier to slow the car down and cars tend to skim gravel. Its also said to help keep cars in the race, so keep the interest in the race. The main argument I can't disagree with, though I am asking whether its necessary. The side point I think is not beneficial, most of drivers making the errors are not in a position to fight very well anyway and there is more excitement from seeing a driver on the edge almost loosing it on grass than seeing them easily recover from the tarmac.
