Sadly living closer does not always solve the problem. I talked to a guy that lives in the Los Angeles area and he lives close enough to walk to work. His problem is two things first there is no safe way to walk to work and traffic is terrible when it takes over an hour to get 5 miles.
Old Mechanic sadly I agree about steel not being replaced very soon but maybe for different reasons. If not for the lighter weight or giving more jobs to farmers plant based plastics would to wonders in the rust belt and other places that deal with lots of rust issues.
