Well I agree that street racing is a silly thing to do, especially in such high powered cars. But, I bet nearly everyone here would give the same cars a work out at least once if they owned them. I dont think there is any car enthusiast that does'nt drive fast and take corners quicker than your suppose to. Its just a case of been sensible and respecting other road users.
I follow a kind of plan.
It should just be done safely, and you should know your limits, and then only use 70%-80% of your limits. and always leave a saftey margin incase you mess up. Then the road your having your "spirited driving" on should be a road you know inside out, which you have leant well. Of course if should be deserted with no other users.
Thats the rule I always follow. Every night I finished work and drive home I come along my favourite stretch of road. And yes I like to have a fun drive should the conditions fit. But I believe your best abilities should only be developed on track.
Other Night I was on my way home on the road to meet a guy trapped in a mangled vectra. Now there are flowers at side of the road as he died on the way to the hospital. He was obviously going to fast and when he hit a slight dip in the road he seeminly oversteered into the wall and rolled.
