I went to NYC last weekend and, just like the previous 7 times i went there, subways weren't running normally after-hours (growing up, it functioned well 24-7). This time (last weekend) no subways were running to where I needed to go. The only option was Uber/Lyft. It took me ~$17 instead of the $2.75 for the subway, but I was just glad to have some means of transportation.
Removing Uber/Lyft is a bad idea. But removing Uber/Lyft without first fixing the mass transit system is insane.
