I agree, street racing is a crime and it is dangerous. I also know the highways of Maine pretty well and, you're right, nothing but lots of open space to wreck your car and hurt yourself.
But not in Epping. People live there, and the roads are tighter and busier. It's pretty stupid to drive at 130 mph around there. Hell, the race track is right there, you said it yourself. Racing is meant for the racetrack!
