1. Still not as passenger dense as a train or a bus 2. They will need stop some time. Where? Will this block the street? 3. They won’t all go to the same place so there will be delays at junction and side streets 4. No margin for error wouldn’t fly in practice, so the cars cannot be that close together 5. How will pedestrians cross a train of cars? I just don’t see how this all adds up. Automation doesn’t remove the space constraints of cars in cities.
