The key is total system efficiency,which many fail to note.
Consideration needs to be given to manufacturing costs,fuel origin and delivery,emissions,disposal costs.
Too many do forget the power plants when speaking of pure electrics.
Currently gasoline or diesel have the highest enery density of any fuel we know how to routinely handle,so economically converting that to our travel is the sensible course.
People demands on a car are higher than in the past,look at how basic the VW bug was;now it is rare that a car be sold without an entertainment package,air conditioning,etc.Plus mandated air bags and literally dozens of computers which can fail silently leaving you(it did me) in the middle of the road!
A Prius wouldn't serve my needs well;something like a hybrid Isuzu Trooper would though!
Perhaps 15 years ago one of the popular mechanical magazines featured a new electric motor that envisioned using one motor mounted to each of a car's four wheels therby giving 4WD,regenerative braking,lowering the car's center of gravity,inproving overall weight distribution and perhaps other pluses.
Haven't seen such a car yet;I suspect the government regulations actually hamper new transportation development.
