Very late to the party here I suppose as this is a few years old, but haven't seen them before - no idea why they came up in my feed now, but happy it did. These things are heaps better to watch than the flacid V8 stupercars we have now. They should change it to these puppies - would get their audience back. [biggrin]
Although I guess the Nanny rule makers would have a fit about the safety of them as far as the jumps go and the fact they can swap paint without getting a drive through penalty and everyone having a sook about it.
