    HYBRIDS should be higher priority than all-electrics (And other considerations)

    Absolute priority should be rapid trans. Perhaps not trains where tracks are not. But in most places highways are and "bus-trains" could be the vehicles -- even just "doubles". Eight mile per gallon hauling 70 rush-hour people saves a fortune's worth of fuel compared to, let's say, 60 cars at average (including tie-ups) 18 mpg. Buses can even stop more frequently than trains, such as at highway interchanges where people could park and pool next to the McDonaldses.
    But where there are cars or have to be, it seems the immediate paradigm should be the hybrid. The whole fuel infrastructure and distribution is in place all over the country. The system is proven (if it works for freight train locomotives it sure should work for a passenger car) -- reciprocating engine turns generator which powers motors to make wheels turn. As well, for the car, the motive force can be from the gas or diesel engine alone.

    Hybrid already is. More expensive? Lengthen the period of payment. Savings? efficiency by getting rid of so much mechanical like shafts and axles and differentials and transmissions and a whole lot more. Electric motor at each wheel.
    Power variation is electrical through cable to each wheel's motor. Come to a stop, no engine continues to run and thus burn fuel and produce emissions while the vehicle goes nowhere. (Already some high-end cars have automatic shut-down when motion stops. Instant startup when gas pedal pressed/brake released).
    I think it's a long way to all electric private vehicle transportation.
    I think it's a long-shot, perhaps viable luxury-level system -- but impractical and vulnerable to regional differences in solar collection, distribution via grid (already perhaps critically outdated), and costs of "dedicated" battery rather than replaceables such as used in material handling equipment all over the place already.

    If mass transit, apex-level hybrid (interfacing solar-derived charging) systems, the automobile could still be “de-luxury” for weekend or vacation voyaging, and no longer be one of the most detrimental factors in the depletion of the future's petroleum energy reserves and the present and future further fuming and flooding of
    the environment.
