True. There are other 2 seat dragsters out there. But this is the only fuel car that I'm aware of. There was one in Australia at some point. Cost for a short ride in Dixon's car is 5 figures, plus. And it's been run at non-NHRA tracks. There's a Youtube vid out there of some dude going for a ride, 330' I think.
Not wanting it to run at an NHRA track or putting a tag on it, I can understand. The car is not really legal to go quicker than 10.0s. But they've been mighty heavy handed with the guy for some reason.
