I'd sure think about buying one.
Or something similar with a bit more room.
The key to the future of the automobile is the true hybrid, i.e. an electric car with a charging motor that kicks in as needed. If GM (or anyone else) can deliver an all-electric range of 40 miles, it's going to work very well for a lot of commuters.
To get a car with any decent electric-only range needs lithium-ion technology, which has been one of the holdups.
There may be growing pains with the technology, like any other tech, but I wish GM all the luck in the world on this.
