tldr: I <3 uber and Uber > taxis
I can't stress how important the airport thing is. Radio dispatch by cab is the most unreliable horrible mechanism ever. It almost may as well not exist, because a cab might show up in 5 minutes, it might show up in 15, or it might show up never. Impossible to rely on. Due to Uber being reliable I've taken more car rides than usual to O'hare on days when I'm running late, or otherwise don't want to deal with the Blue Line or waiting outside for a cab.
Basically, cab companies did this to themselves by being horrible at customer service and not giving a shit. They are up there with Comcast in the "giving a fuck" department. Ever call to complain that your cab didn't show up? Ha!
And if you think this is great for a well-served city like Chicago, it's utterly game changing for under-served cities like Minneapolis. I now can actually take a ride to the airport instead of driving and spending $250 parking my car for a week. Why? Because I can depend on the Uber showing up when they say it's going to. Cabs, I'd have to give at least a 2 hour buffer in case the first 2 I call never show up.
Basically if this puts the cab companies out of business, it couldn't have happened to better people and I won't shed a single tear. Good riddance.
Without reading that entire document, lets just say NYC is a $20bn+ market for the taxi industry...
