While I admire your insights into the present catastrophe I might disagree with the long-term solution. Nature is the most efficient and it gives each creature it's own mobility but it does it only with transferred solar power. So, electric cars that are solar powered (but owned by the public) could revolutionize urban transport, especially driverless. It's like mass transit but more fluid and dynamic and it would free up all the space dedicated to parking. Bicycles are for the young and strong and they too are plenty hazardous for pedestrians.
