viperdrummer: I said track mistakes are "sometimes" more foregiving. What I mean is that tracks often have runoff room so if you make a mistake, you don't run into a ditch, tree, mailbox, pedestrian, etc. There are obviously areas of tracks or situations that are not foregiving. You also usually have your tires operating at or near optimum temp on track where street may never get to proper temp.
Vipers are similar to guns. In the proper hands/environments niether is dangerous. Add an inexperienced operator/poor environment and both are dangerous. I see an aweful lot of wrecked/totaled Vipers, probably a much higher percentage than other cars, especially comparable cars with nannies. I let my 18 year old son drive my Caddy (occasionally) but he has never driven the Viper, and I have had him through a very good DD school. Just don't want to take the risk of a simple mistake becoming catastrophic.
My biggest example is if you let someone drive your Viper and they decide to "floor it" they likely will get in trouble. They decide to "floor it" in the Caddy and the nannie corrects the stupidity of the operator. My opinion is that in and of itself a nannied vehicle is safer than a non-nannied. Kinda like handing a loaded gun with NO safety to an 18 year old. Probably not a good idea. Nothing is a substitute for an educated/skilled driver and common sense. Problem is, there are not enough of these around.
