"The rocket planes, or X-Racers, will compete on a course two miles long, one mile wide and about 5,000 feet in altitude--right over the spectators. "
Gee....that could never end badly!
As far as NASCAR goes, it's really boring if all you watch is the big tracks (Daytona, Talladega, etc) where half the drivers are running scared of the "big one". The shorter tracks have plenty of action and crashes are actually annoying because they interrupt the race.
