To win a five day road rally, you have to visit the site five times, of course. Several motivations are at work:

Fun
You will come back because it is fun. It's novel, and challenging.. and it's free.

Prizes
The big prizes go to the best drivers, of course. But in a brutal rally like this,  it is an honor just to finish the race. Finish and you're entered in a drawing for cool gear.

Competition
You've got to return and defend your position - or catch up if you have slipped behind.

Reminders
When you complete the day's driving, you see where you stand in the pack. But other drivers are still coming in. At the end of the day, you  get the final results by email.

Second Chance
Got beat? Come on back-  try again. Maybe you'll  improve your results.  Why not?
