It's a bit of a misconception. Soft-sprung cars can be hella fast on roads.
But modern supercars are sprung so slow for downforce, to try to turn their bottoms into vacuum cleaners. But (outside of racetracks) its mostly for show and 'sporty feel,' as this downforce doesn't really kick in till like 90mph+. In fact, many racecars are faster around hairpins when sprung looser and higher.
