Is there something I’m missing, or do cyclists have to stop only because motorists would take a tantrum if they weren’t required to?
Motorists would make a tantrum regardless, and they don’t stop too! Rolling through is very common; indeed expected in many areas. After all, how is a town supposed to enforce all of their intersections? For example, San Francisco has 18,525 intersections and 2,140 officers. Assigning 10 intersections per officer and to ignore all other police needs would be insanity. They’re trying their best but it’s an uphill battle.
Amazing, right? They’re a shop oriented towards trike builders. Not only do they have by-the-foot orders for a trike’s crazy long chainline, but they offer a la cart parts on their kits! Not just for repairability but also for whatever custom project you’d like to lego together. I’ve had nothing but good experiences with them. :)
