A good example of how good ideas can suck with bad implementation.

NYC has a paratransit system where you can essentially do something like this if you have a disability that stops you from taking the train (there's still lots of subway stops without elevators, etc). From my understanding it's nice in theory but borderline unusable given delays, ahead-of-time scheduling, and the endless gridlock in the city. So basically there to tick an ADA box...
