On an episode of "American Muscle Car," there was a segment on the Dodge Viper. During this episode after showing some wonderful GT racing, there was talk about a certain Viper that was called "King Snake," I believe it was. I think it looked a lot like what you'd see a professional drag racing team race, but it was street-legal and put in some wicked ETs.
I don't know who had it or something, but it's kind of rare to see a Viper in drag racing. And I say it's rare in drag racing because the Viper (unlike some muscle cars) made a name for itself on the road courses). Of course, never count out American cars for doing only straights and ovals. But as far as drag racing goes, almost ANY car or truck can be used. Don't just assume that American cars are going to own the strip. Perhaps we can have rather unusual events including drag racing Lotus Elises. Maybe you want to have VW Beetles in action. Maybe you want to put the Toyota Supra to the test. Or (98Cobra, you might like this), you can have your own NMRA (National Mustang Racing Association, if I'm not mistaken)-style event in GT4. And as I said, I don't think GT4's drag physics will be crap. There's drag racing in Japan I've heard of. I don't know if PD would work off of Japanese drags, FIA Drags in Europe, or American drag racing. Whatever it is, I'll perhaps think it will work successfully.
But if I'm not mistaken, wasn't drag racing supposed to be implemented since GT2?
