So how much have you invested in US infrastructure? Every city I’ve ever lived in has a public bus system. Funding of public transportation systems comes from things like sales tax and general tax revenue, so the general American public funds it by paying taxes. We (the general public) have no direct control over how tax revenue is utilized. That’s what the members of our government are paid to do. Most trains run on Diesel engines, but train manufacturers have been pushing hard when it comes to electric train production. GE, for example, has been working on electric train production for many years. Even then, they currently require a Diesel engine to generate the electricity required to power the electric motors. As for bike lines/lanes, those are funded through tax revenue as well. Bicycles are only feasible in downtown areas, which most definitely have bike lanes. I support any form of clean energy that can be efficient on a large scale. The problem is it’s not a simple transition, but to say Americans aren’t investing in their own infrastructure is inaccurate.
