The Volt died due to lack of marketing because GM didn't really didn't want to make it due to cost.
The problem is that all the car manufacturers know that hybrid is a dead end. So, everybody wants to produce all-electric since all-electric is ridiculously cheaper to produce than hybrid or combustion engine cars.
In the meantime, back in the real world, the infrastructure for all-electric is rolling out very slowly. This means that you need to be a short-distance (read: larger city) commuter who owns a house with a garage parking spot (read: stupidly expensive real estate because in/near larger city) in order to take advantage of having an electric car.
So, nobody wants to roll the infrastructure out since that's expensive and there's no lock in. And the manufacturers don't want to roll out hybrids since those are a dead end.
(Good example of the brain damage: The Oceanside train station in San Diego has a couple of electric parking slots. The first problem is that there are too few--every spot should be electric. Second, you are only nominally allowed to use them when you are actively charging. This, of course, is stupid since you're likely to hit your charge maximum sometime when you are 100 miles away by train. Third, there is no useful shuttle from anywhere to the train station so that you could put your car there as a freeway stop and "top up" while you go shop, eat, etc.)
