They're always more common in metro areas of the US. You must be from a relatively rural area and don't get out of it much.
That said, uh, the use of getting a taxi to drive you to or from the airport was just not having to park at the airport which generally costs a lot of money, and in certain areas is a little sketchy on whether or not your car will get cracked open while you're away.
That's a little reductive. I grew up in San Diego and went to school in LA and had the same experience with taxis - never took them. But now I use ubers in those cities whenever I'm there.
The US has tons of cities like this that I imagine would have issues with taxis - all parts of the bay area peninsula / east bay, cities in Texas, Denver, etc. Most cities are not like the NYC/Boston and even in places in Chicago, unless you lived downtown likely didn't see taxis driving around.
