I think that there are a few things that can make these cars safer.
1) Understand what it is your driving (Cobra, Chevy Malibu, Ford Explorer -- whatever car)
2) Honestly evaluate your driving capabilities. (driving school is great place to do that)
3) Drive to 60% of what you believe to be your limits. Don't risk finding out that can't handle a situation when you are into it that situation.
4) Learn the roads you drive on and the laws that apply to them. That means knowing what the shoulders are like (soft, gravel, paved) what dangers are on the road (turns, animal, children). What other vehicles typically drive on the road? I will often aviod interstate 95 because of the trucks and take the Merit Parkway that only allows passenger cars.
5) Slow down in congested areas. Most people want to have their cars admired anyway. Give people a chance to see them!
6) Pay attention to what your doing. No cell phone, drinks, grabbing your passengers goodies
7) Drive fast at the track only.
