Not when we still have junctions, traffic lights etc
Yes when we still have junctions, traffic lights etc
Your counterpart, from even further back in time, would have objected in the same way when they first tried to take his horse off him. All it takes is coordination between vehicles, their navigation, traffic lights and you could choreograph in real time, away from blockages and into openings, making streets temporarily all one way or one way streets bi-directional, on demand to suit the time of day or a leaky water main. We're on day 1 now, there's no reason why this couldn't be in place on day 10,000.
Sorry but I'm with Jetpilot on this one, ...never going to happen imo.
Far too many variables.
Even if they got all the cars, traffic lights etc as you say in some choreographed synchronization some tw*t on a pedal bike would spoil it all anyway.
