Really? Interesting. Which direction from Philly is your suburb? I've been to a decent number of cities and their suburbs and usually found Uber or Lyft to be available in the past year.
Locally, living in either Jersey or Connecticut, Uber/Lyft have been available for a while now wherever Ive been in those states. I do remember when taking an Uber or Lyft from a suburb 40 minutes outside of NYC in NJ, the driver complained that he had two tickets from Philly airport.
Are Philly and perhaps the surrounding areas in PA just more strict still with laws? I know Uber made a big push a year or two ago to be available in all of Jersey. And since Philly or say, Hershey Park, can be pretty close to a portion of NJ, I assumed it was available there in mass too.
