From my experience w/ RC, I like electrics. Also, being a minor history buff, I've read about about the early electric cars, and have followed electric bike & car articles for a bunch (25+) years. At some point, battery and controller tech will make electrics cost-effective alternatives to gas-powered vehicles. I believe that current government subsidies both delay and corrupt that process. When businesses make money for "trying" or "treading water" instead of actually progressing, it is too easy to get off track. In so many cases, we see businesses who are focused more on the subsidies than on the product and its cost and quality. So again, the total cost will be higher and the timeline longer, but the products will eventually come in some form.
For now, short-range and expensive. Toys for the gadget freak, the well-to-do, the innovator, and the poser.
