We have all seen Prootypes testing at the Dragon Here is another one. 2016 Chevrolet Camaro Prototypes Spotted Near Tail of the Dragon
I don't remember when, think maybe it was 2 years ago. There was a brace of new sporty Caddies at Fontana one of the Weeknights. Spoke with the engineers driving them in the lobby for a while that evening. Quite fascinating talking with them. It did give me a deeper understanding of the compromises built into vehicles.
It's not a big deal. Lots of cars drive on the Dragon. Lots more test their wares there. We MINI people need to realize that we, too, are among the pack of cars that drive on the Dragon. I think we must remember that the Dragon was not created for us...after all, it was a motorcycle mecca for years before anyone ever thought about bringing cars there. Just my 2c, fwiw.
