I guess what I am trying to say is that while it is dangerous (you're going fast on a motorcycle and things can happen), it is also much safer than trying to be Johny Rockets in the canyons... there are no cars, no cops, no deers crossing the road, no oil (normally) on the pavement, there's an ambulance right there in case...etc... and control riders (with flashy yellow vest) in all groups (more in group C) that are supposed to make sure everyone rides safely, and you can ask them for help at anytime... they will ride in front of you to show you the line, or behind you to watch you so they can give you advice later (or in the hot pit, during your session).
In other words, while it's not a "safe sport" per se, I would highly recommend you try it out! Don't let the risk stop you because I believe the experience is well worth it, and may give you that confidence you need to be a safer rider on the streets :rockon:
