Some cities seem to get far better rates too. In Boston most of my trips were around $4-5, maybe closer to $15 to get to logan. When I was in Columbus it was like the trips were arbitrarily twice as much, hovering $7-10 for similar distances. Miami probably had the highest rates I've experienced (Like $25+ to get to the other side of the biscayne bay), traffic was terrible as well so I wasn't as shocked, but it seemed much higher than going a similar distance in LA. I was still able to get rides in 10 minutes in most cases everywhere, so it wasn't for lack of free drivers, it seemed.
