Should motorbikes and cars share lanes? How to deal with left turns (the dangerous ones) in junctions? Should motorbikes and bikes have to do two-step left turn?
There’s an idea that we should categorize vehicles as human-poweres or not. Is this a good idea? How about paddle-assist-only ebikes?
When there’s not enough space for lanes, which type of vehicle get compromised?
Two levels of roads. Cars on the bottom and everything else on top. Probably better to do the opposite if you’re in a rainy place, but cheaper to maintain elevated roads for bikes and peds than cars and trucks.
