In a way, I agree. Touring cars are darn exciting, and the racing is close and very competitive. I try to watch as much touring cars as possible, from DTM to BTCC, to the Aussie V-8's. All good stuff. That being said, I still consider F1 as the cutting edge of racing, it's the sharp knife in a drawer of plastic spoons. To me, there's nothing that comes close to F1.
F1 is big money, big expectations, incredible, unrelenting pressure on all participants. It's a pressure cooker, where the weak quickly fail, where only the strong survive, let alone win. Yes, the politics and crap are a burden, Max and Bernie run a very weird circus.
But even with all that, Formula One is the big show, the ultimate form of road racing.
But it does take it's toll, Formula One is littered with the shattered dreams of many drivers, teams, and supporters. But sometimes drivers with nothing to prove, drivers who are recognized as highly competent and skilled decide to step away from the pressure and crap of Formula One, to salvage their piece of mind and sanity, to go elsewhere and just race for fun. Just like Mika did.
