I can tell you that I'm all about my own personal preservation, regardless of where I ride. I ride my own pace on the street or the track. When I do want to push myself it's always at the track because it is safer than on the street. I agree with you Speedy, that riding within your own limits should be #1 when on the street or anywhere for that matter. But some peoples idea of their limit is way too high for their actual riding skills. These are the guys that think they can back it in to a corner on the street and that picking gravel out of their road rash is cool.
