RPDE does a lot of different tracks, but the cost is extra at Indy and Daytona - I wonder why.
Anyway, RPDE is a lead-follow experience. You drive your own car, but follow a professional driver at a few car lengths off his/her rear bumper. RPDE does also have "ride alongs" - saw an 80-something grandmother take one the day I was there.
And yes it's an absolute blast to drive. That car was easily the most powerful thing I have ever driven - somewhere in the 600-700hp range. It'd put you back in the seat at any speed. And the sound and smell of the engine was awesome in the cockpit.
Would I do it again? . . . (long pause for at least 2 milliseconds) . . . Ohhhhh Yeah!
I'd also love to try the open wheel thing . . . Now if I can just figure out how to drop a couple of hints to Lorrie for my next birthday . . .
