Here's my take:
The car is still misunderstood. I get all kinds of odd questions about running out of electricity. And then people say on gas it only gets as good as any other car it's size. Yes, you have to used the electricity to save money-if that's your goal.
There is a perception it's a pain to plug it in all the time. Yes, it takes time, but not that long compared to stopping for gas.
The upfront cost is a lot. We have been trained to be a disposable society. 40 years ago we repaired the TV (they were expensive), now we throw it away and get a new one, it's cheaper. People are used to paying less. So if they start comparing the car to an equivalent car the same size, the cost looks huge. People don't want to wait to reap the benefits (financial I'm talking). And yes, the car is loaded with a lot of nice features.
It's not the car for everyone. The technology is there so PHEV's can become cars for everyone. But the Volt itself is not for everyone. It's great for our family for ONE of our cars, but we couldn't realistically have two of them.
People are accustomed to certain things. Like power seats. A suprising number of people have made that comment they should be standard on a car that costs that much. Me, I don't care, as I am usually the only one driving. I do wish it had tilt adjust for the seat bottom and lumbar.
But GM does need to do better marketing, and most people simply misunderstand the car.
