Hamilton just signed a deal with Mercedes for 3 years, $100 million. I'm sure that $100 million is including incentives based on performance though. Vettel signed an extension with Red Bull a couple years ago that was rumored to be in the 3 years, $80 million range.
Comparing drag races to driving around Monaco. I know OP is trolling, but I'll still bite seeing as I'm an F1 junkie.
Granted, there were more street circuits in the past than there are now. There was a pretty demanding one in Phoenix, for example. Think it was last used in 1991. Also ones in Adelaide, Detroit, Long Beach, and some more.
And as mentioned before, they still do 78 laps of Monaco, one of the toughest street circuits, and has been for years. And Valencia too, though can't see them staying there for much longer, track is apparently very run down.
Too busy living the life, and I don't blame them. People think street racing is cool based off films like Fast and Furious. Dunno why, but I'm not a fan of nice looking cars being disfigured with **** ugly spoilers and awful paintjobs. Hardly the height of technology either. I'll stick to the pinnacle of Motorsport thanks.
