IMHO -- one of the biggest obstacles to racing is the perceived danger.

Racing IS dangerous, but the general public has been trained to think if you race your car, you'll wreck it in almost every race. All the racing highlight shows concentrate on the accidents (among other things.) and rereally lurid ones make it to the opening graphics for the races (remember Joey Hand's big end-over-end crash at Mid Ohio? You see it at the start of every ALMS broadcast now.)

TT deals with that a bit, once you get through to them that time trials are fundamentally different from w2w, but even that can be difficult.

What we need is a way to demonstrate to the public that our kind of racing isn't as dangerous as they've been led to believe.
