Uber Drivers -- Mass Exodus To Phoenix For Super Bowl $$$

Super Bowl? More like the Uber Bowl ... 'cause TMZ Sports has learned Uber drivers from all over Arizona are headed to Phoenix in droves ... hoping to cash in on that crazy Super Bowl traffic.

A rep for Uber tells us ... they've noticed a surge in drivers heading to Phoenix this week (from places like Flagstaff and Tucson) ... and it seems pretty obvious why.

With a full week of parties, events ... and of course the mad rush to the big game (surge pricing?) -- there could be A LOT of money to be made this week.

But get this ... Uber says drivers from out of state are out of luck ... because Uber drivers are only authorized to pick up passengers in the state where they are registered.
