Driving in Tucson is misery incarnate.
A significant amount of daytime rides involve ferrying students from one part of campus to another, for the minimum fare, down streets choked with other Ubers while pedestrians and cyclists pass you.
Any time a surge hits, pings stop altogether, and you suddenly notice full taxis everywhere. Then as soon as the surge ends, you are pinged by someone on campus going from one class to another.
At night: substitute "campus" with "4th avenue", and "class" with "bar." Add puke and stir!
