The only big negative unfortunately is the "on the road" charging network ... or should say, lack thereof. Unreliable, poorly maintained charging stations that are a crapshoot if they are working can kill enthusiasm for EV's. Charging at home of course is no problem but leaving your home charge radius can be nerve wracking. GM should pay the money if they are serious and install a RELIABLE charging infrastructure sooner than later instead of relying on the (mostly) amateurs that are out there now. Take a page from Tesla ... this is a major reason why people are buying this brand.
