The NYC buses require you to take the kid(s) out of the pram and fold it up. A total PITA
Another kvetch: using car seats in taxis. Maybe it's different now with Uber but 20 years ago the drivers hated it because you have to find the seat belt and secure the car seat...
NYC parents already know this and have strollers that fold up to backpack size. The stroller market has progressed incredibly in recent years, there are strollers designed to fold with only one hand.
Ubers/taxis with car seats are no big deal as long as you’re quick about setting them up. And even then, kids are only in full blown car seats for a few short years.
