“They put a single bike lane on a single street and no one used it!!”

I doubt many people would use a road for cars if there were only one and you had to drive on busy railroads to get to it. Same logic applies to a bike lane surrounded by car-centric infrastructure. You need a network, not a single lane, if you actually want people to use a means of transportation.

That’s ignoring the fact that drivers consistently underestimate how many people actually use the bike lane.
