Formula 1, Ralley Racing, Drag Racing, Funny Cars, Nascar, Nascar Truck Racing, or Motor Cycle Racing?

And if you could do one what would you choose?

If I could do one I'd choose Formula 1 just because I love the cars and the sport is so fun to watch. Also my second choice would be Ralley Racing. I don't know those two would be very close together cuz both are very awesome to watch.
