Hybrids are under discussion already. I've just been thinking about some issues that I haven't been hearing addressed in regard to the purely or primarily electric rides on the horizon. GM at least keeps talking of 40 miles on a charge. What about the majority of the year in northern areas where you need a heater and defrosters running? Isn't that going to cut down the range substantially? Under what conditions are the engineers & promoters projecting a 40, or whatevr. mile range?
