I understand the frustration but also bikes take up a lot of space. When someone brings one on the NYC subway at rush hour it’s definitely an inconvenience.
In Berlin you just have some areas in wagons designated as bike areas. They are still cramped but you can be there with your bike. Plus you pay extra for your ticket to bring the bike.
I feel like the failure here is that it gets so packed that there isn't space for a bike. Because it's not just bikes impacted here. If you can't fit a bike, you can't fit a wheelchair, you can't fit a pram, you don't have space for someone who needs to sit down, or someone who can't handle being pressed in at all sides by other passengers.
It's a wrong allocation of resources where we decide everyone can have 4 empty seats to drive to work but we can't fit 1 person and a bike on PT.
