Nobody is suggesting anything of the sort. In a given area (say a full city block, including all roads and alleys within and bordering that block), you might want... - Pedestrian lane - Bike+scooter lane (any transport that's ~20mph and <500lbs loaded). That may or may not include gas scooters (50cc Vespa type). - Auto lane - parking lane (could be a mix of bike/car parking) - possibly a transit lane (bus, light rail, etc) And you don't need every one of these on every block/street - you can alternate. Or use one-way auto lanes on alternating streets to make room for the other modes of transport.
