Having a fast car like that also makes road diets less effective, if a car can get up to 60mph in an instant after a speed bump. The altima would take say 10 seconds of the engine sounding like its very angry with you, there wouldn't be time to get up to 60mph before the next speed bump perhaps, and if you drove like that everywhere you went you'd get like 10mpg maybe.

It truly makes no sense why the NHTSA seemingly works so hard with crash testing, yet they see no problems with a 5000lb family sedan that goes faster than a Ferrari F40.
