This assumes building a fast charging network, not just along main freeway routes, but at every workplace, shopping mall, restaurant, movie theater, and any place else where there is public parking.
I still say this is trying to turn an EREV into an EV.
If it is a deal breaker, then so be it......
What we need is more vehicle choices instead of one vehicle with all options. What is this, the Bradley Fighting Vehicle? Someday when the Volt is not the only EREV on the road, people will stop trying to make it do "EVERYTHING".
