>>With all due respect to the dead man, its asinine to allow novices onto a racetrack.<<
If the top speed is 120, it is hardly a “racetrack”. Also, if he was alone, he wasn’t racing. It is probably the safest place in the country to do those kind of speeds.
There are plenty of racetracks where you can't drive at 120 mph in any car. In this instance, though, it is the car that is the limitation. They are probably de-tuned to an acceptable performance level for student race drivers.
Nascar cars are not particularly quick anyway, they have nothing like the performance of Formula 1 or even Indy Cars. For instance, the Nascar lap record at Phoenix's PIR is 26.499 secs (135.84 MPH) Whereas the Indy Cars routinely lap at 20 seconds or below which means they are averaging 180 MPH or more.
I know of an AC Cobra that holds (or held) the production car lap record at Daytona at an average speed of 198 MPH. So, the thrack is not the limitation in this instance, Daytona is a Super Speedway.
