I love how the shape of that new Jaguar calls back to the XJ220! Japan would be the place to field a series that's crazy without being a circus. I too would love to see an all out series but I wonder the extent that humans will be in the car. F1 cars are already pushing 5-6G's in the corners. Perhaps drone-style racing will be where we see insane race track tech. However that tech might quickly diverge from anything that can be applied to road going cars.
