I'm thinking that a lot of people are overlooking Hydrogen cell fueled vehicles. Yes, it'll mean stopping at a fuel station, and eventually, we might get gouged again price-wise? But we can produce our own hydrogen at home right now. At this time I do not know of a system that can produce enough (homemade) hydrogen to supply a vehicle, but the way technology is going it won't be long before there are systems; as long as there is consumer demand for it? With hydrogen, there is no high voltage battery pack to power the electric motor(s). There's no gasoline or diesel-fueled engine to charge batteries or power the vehicle. Safety-wise, if there's an accident that ruptures a fuel tank (cell), all hydrogen wants to do is head for the shy and as fast as it can! Where does gasoline and diesel go, possibly feeding a fire?

Sorry but duel fuel (Electric/fossil) is a double jab up the ass. One last thought, what is the environmental impact of building all these batteries? Let alone what do we do with them when they are burnt out? Dig a deeper hole to bury them?
