Imagine all the problems that would be solved if someone invented a car with metal wheels, maybe one that can hold hundreds of people, goes really fast, is quiet and efficient....
...and can only go to select locations at certain times that may or may not align with your final destination or schedule.

From the article: >Rubber is also considered plastic, both natural (isoprene) and synthetic (styrene butadiene).
Definitely not what comes to mind when I think of plastics. I usually hear Bakelite quoted as the first invented plastic.

The last mile problem can only be solved by eliminating single family detached homes. You can only reduce the amount of energy required to move bodies so much, at some point you have to start reducing the distances traveled.

I thought I was doing well picking better tires than factory for my vehicles but it turns out any new tire would have had better handling because it was new.
