Personal vehicles are probably the most challenging vehicles to electrify cost-effectively. (Dragging one or two passengers around over long distances in a 2-ton vehicles takes a lot of energy.) Electric busses, on the other hand, are the ideal candidates for electrification as they can transport dozens of people while generating far less pollution per-mile when compared with a car or diesel bus. For a country that relies heavily on urban transport, the US is set to benefit heavily from electric busses.
