If I was a millionaire, I'd have that in my game room, along with a really bad ass flight sim set up
If I was a billionaire, I'd have my own track, a fleet of cars (with techs to work them at my beckon call!), smokin' hot umbrella girls, a beer truck with a tap off the side and all the time in the world to race around all dang day long.
Since I'm neither, I'll just stick to my PC games...
