I used to like to watch truck races.
Semi's that is. No trailers, but full sized diesels. I think they were popular in Australia.
Also, the Paris-Dakar Rally has a class for large trucks. These thinks look kinda like garbage trucks -- they are that big or larger - -and they race several hundred miles through the sands of northern Africa. Neat to see them get big time air as they come over the dunes.
Also, back in the 70's or 80's there was a demolition derby run for charity. Cadillacs, Rolls Royces, and IIRC, a Ferrari or two.
