I also thought it was a bit of a wild request for bikes to only cross where bike infra exists. If we can’t make progress in driver behavior, we should build more mode separation to contain the thousand pound death machines in their own physically isolated section of the street. At no point should we be compromising bicycle or pedestrian mobility. We have a right to the street also, and it’s the cars who have trouble co-existing with the other modes of transportation without murdering a bunch of people.
