Outside of Tesla, the EV marketplace is still in its infancy.
10 years ago the Nissan Leaf, Smart Fortwo Electric Drive, and Mitsubishi i-MiEV were the only games in town that had a ghost of a chance of securing over 15,000 global units a year.
The Chevy Volt was/is quite a nice PHEV. If you removed the $7500 tax credit I would still argue that most new car buyers would actually be better off with a Prius Prime Plug-In if fuel economy and emissions reduction are their priorities.
My concerns are more geopolitical. We're forced to work with those who frankly hate the American way of life as it stands right now. In a world where we intentionally choose to minimize our dealings with the Arab dictatorships, Russian mafia, and the Chinese communist party, hybrids and the PHEV would be the vehicle of choice.
Every dollar we keep between America and our allies is a dollar worth keeping.
