In the three fastest formulas all the pilots are solo : Champ Cars, Formula 1, MotoGP.

Two person vehicles are available but they are for the experienced pilot to give the novice passenger a thrill.

So use logic, not metaphors.

Those are all "go fast, turn left" racing, with relatively little navigation load on the driver, and almost no way to get off track. Memorize the course, plan your strategy and tactics, and run the course over and over. (Not to trivialize the skills required.)

Rally and programming have lots of chances to go off into the weeds or get off course.

"go fast, turn left"?

Are you confusing Nascar with F1? Seriously?

[nfnaaron]

No, just that the track is limited and easy to navigate.

[getonit]

It's pretty easy to tell them apart - if you see any overtaking, it's Nascar.

Good, cheap, fast. Pick two.
