If money is not an object, I might agree. But money and financially sustainability are part of the equation. In fact, money could be loosely used as an indicator of planetary resources. More expensive is roughly a requirement of more planetary resources.The only thing that appeals to me about sustainable transportation options is that they are sustainable by this definition: Any form of transport that does not use or rely on dwindling natural resources. Instead it relies on renewable or regenerated energy rather than fossil fuel that have a finite life. I think future generations will be grateful to those that adopt the philosophy and supported the technology to make it happen. I think we need ICE, hybrid, and PEV options. Drive what you like, Like what you drive.
This is why an Elio at or near the target price and fuel efficient works for me. Plus, I'd agree to eat a formerly flatulent cow a year to offset the ICE.
