The Chaparral 2j is one of the most inventive and cool looking cars I've seen.
Not f1, Can-Am but yeah, I'm really surprised this isn't a more common approach to modern track cars. Obviously banned in most motorsport but I'm surprised with all of the one-offs these days that it's not more common.
Because nobody wants to be on a road/racetrack with a car that will pelt the car behind it with stones it pulls from the tarmac
