It would be more fun actually doing it than just watching it.
All I have to play around with is a really old car that it pretty much broken down. Haven't driven it in at least 6 months though so I don't know how well it will work now. I just do 180's by pulling the hand brake on it. Mud is fun when you get the wheels spinning as you do donuts.
I've never driven a 4 wheeler. As far as that stuff goes, only a go kart, which we don't have anymore.
Dunno anyone that has one... Can't afford one myself, want a newer car over an atv... I'm sure it would be cool, especially on my land with 500 acres to drive around on, but kinda hard to do when you don't have one, lol.
