I live in Cambridge and agree with the reasoning as a driver and a cyclist. They put a bike lane inside the car parking area along the main drag (Cambridge street) i live on. It’s hard as a driver to make sure the lane is clear before turning, and when cycling through you still have to be careful and look before crossing the side streets.

It’s still better and it’s been a year since I saw a bicyclist and a driver have words when the car failed to yield.
