But most people aren't littering the bikes. What you get is a bunch of people attempting to hack the bikes and they leave them anywhere, along with drunk and disorderly people that kick them over. Why are you punishing all the people that leave them properly parked?
It reminds me of how taxi drivers kept objecting to Uber.
Yes, we need more parking bays and that's on local councils to provide, but leaving them anywhere helps everyone. I've never seen a Santander bay South of the river for example.
Punish the bad actors. London has more CCTV than any other city in the world. Put it to good use.
