The full aerodynamics package version (aka the flying car) is invite only and apparently mostly for show. But the basic suction fan and gas thrusters version for acceleration will definitely make people go crazy on race tracks. Imagine a Top Fuel dragster-like acceleration in a car that can go more than 1000ft. Heck, if they set up a real league with this, it might get me back into watching motorsports for the first time in a decade.
Personally, I find that the more tech there is in a motorsport, the more boring it is to watch. F1 being a prime example. YMMV
I wonder if the Roadster can seriously compete with the McMurtry Spéirling Pure. It’s lightweight and has crazy active aero. The Roadster has the thrusters, but I can’t imagine those lasting long if the race is long enough. (i understand it “refuels”, but I can’t imagine that being quick or energy efficient).
