I live in Michigan, and especially since Covid, many of the small towns in this state have no taxi or rideshare options. Cadillac MI is one example - big enough town that there's some stuff to go do, but only a single taxicab and no rideshare. The single taxi is fairly unreliable. The saving grace at Cadillac is that the airport has a courtesy car you can arrange to borrow, but that's more and more rare.

Ground transportation at a whole lot of the places I can fly to is just nonexistent or not at all reliable. I expect much of the rest of the country probably has similar issues..
