"Because nothing else is based around the idea of building a light car with a turbo engine that runs at 15k rpm minimum."
The american indy and champ car series get pretty close so its hardly unique.
"And can withstand 190miles (Silverstone) continuously."
Wow , a whole 190 miles. Incredible. Thats only 1/1000th the distance a good road car engine can manage but hey, yeah , I'm impressed!
Rest of blah blah snipped
"(enough?)"
Not even close. Rally cars take far more punishment plus the the racing is actually exciting unlike the tedious procession of F1.
