What can we do to minimize car usage and petroleum and other car energy consumption? I was thinking designating some car lanes as bike-only lanes could work in some places, or even having an hour where only bike traffic is agreed or something like that.
Bikes could have special carts attached to them for transporting whatever messed to be transported during those hours, and some special vehicles would be nevertheless authorized.
How would this work? Where has a similar system been implemented, and what are the details?
