Let's say we change bike lanes to be open to anyone, as long as they are traveling, say, 15 mph or slower, and no one is allowed to traveli in them at a speed faster than 15 mph (not even bicyclists). Their purpose would be for all vehicle drivers who are decelerating to park or turn (once they slowed to 15), and for cyclists, scooter operators, etc., who are traveling at 15 mph or slower.
If we did that, then calling them "bike lanes" would no longer make sense. What should they be called instead?
Slow edge lanes?
