Well I have been past the 120mph speedometer. No idea how fast after that, the car accelerated for a long time.
I see nothing wrong with driving at high speeds (above 100). As lond as NO ONE else is on the road, it is well lit, smooth, and there is a considerable clear view of the road ahead. No doubt some will say this is immature, you will kill yourself, etc. I am a member of Fire and Rescue and have seen how car crashes can tear humans to pieces at speeds of 40mph. As long as an individual knows there limits, has some driving abilities, a good car, and doesn't endanger other lives, Go see what that car can do!
After you reach some top speed safely, you will realize it isn't that exciting, and you will probably enjoy fast accelerating, and a cars handling more.
