Yes, their top speed is much much faster. But put that same vehicle on a 1/4 mile race track, racing a top fuel dragster. The top fuel dragster produces around 5g's at launch, the top speed cars are very very slow to build up speed. So much so, they usually require a pilot vehicle just to start them, like you trying to start pedaling your bicycle in 5th gear. You'll want a push. It's a different type of racing.

> Not much faster land vehicles than those.

Its a poor choice of words, perhaps 'quick' is a better word?
