Is the dream of a highway filled with electric cars essentially bunk? First, there needs to be some sort of charging infrastructure in place to get people to buy the cars, but this will only be built when people are actually buying them! Further, suppose a company or government starts building charging stations, in order to build a usable network. If they are built today, we're essentially stuck with today's technology in terms of battery charging, aren't we? Things like adapters, currents, voltages etc. need to be fixed in advance, without knowing what tomorrow holds. Given how fast battery technology advances, isn't this a losing proposition?
