What I would like is basically rebranding bike lanes as low-speed mobility lanes. Take the parking and/or right lane full-width, put up bollards, and zone it for vehicles with a max speed of 20mph (bike, scooter, trike, hoverboard, electric wheelchair, who cares - if it doesn’t pollute and takes up about as much space as a person, it’s welcome). If space allows, add protected parking spots for pickup/drop off and handicapped parking and tell everyone else that they need to pay market-rate for parking.
