For most people though they're only ludicrously faster than the other cars up to 35 (ok 40) or 65 (ok 80) miles per hour. Otherwise the number of cup holders is a more important spec than the handling and horsepower.
That said, I own a sports car despite being aware of this because I love driving it. It's much more enjoyable than an econobox even if that guy beats me to work owing to lane choice.
