Droooool...
My Pontiac G8 has 370HP, and is scary enough. I think that if I had 600+HP, I wouldn’t last a week.
People rag on the computer nannies, but they do seem to work, and that’s a good thing.
Yes, the nannies are OK. I have a 350 hp 370Z. If its a little wet out or I get too feisty, the computer takes over and tells me to grow up. Having the nanny take over when losing traction and starting to skid in a turn is an eerie feeling.
