Even at this late date, the automakers have yet to sell so much as just one plug-in hybrid.
Not that that's going to save the planet. By itself it won't.
The world simply must transition from the Internal Combustion Engine to Electric Drive.
Nothing short of that can halt the advance of Global Warming.
The longer they delay, the sooner the automakers must be transitioned from internal for-profit management to non-profit organization/non-governmental organization control complete with citizen oversight.
