I was struck by how cluttered the bike lanes are in this video of discussing business practices during bicycle commuting:
Just the first five minutes reveal a startling amount of clutter on the bike lanes, with cares parked and people randomly walking into them. I think this is Williamsburg in Brooklyn, based on the soundtrack. Now, I have recently been a bit sore at bike riders as they don't seem to have any conception of social distance.
But this is also a sign that it's hard to make protected bicycle lanes work effectively in a large city with a lot of cars. And that is unfortunate as making dense cities work for alternate transportation is a huge step in the goal of reducing climate change.
We need to do better.
