    It's a much more near-term approach than hydrogen, and far more efficient (read: scalable).  Beyond that, for any vehicle (gasoline included):

     * Vehicle mass reduction, esp. a switch to composites (which will also increase vehicle lifespans and safety)
     * Vehicle streamlining (we need to stop letting unaerodynamic style trends dominate vehicle design)
     * Increasing use of hybrid technology
     * More widespread adoption of LRR tires
     * The continued incremental progress in ICE efficiency

    There's no reason why two-seater hybrids shouldn't get 100+ MPG, and four-seaters 70+.  If you let streamlining and composites/weight reduction dominate your design process, you absolutely can make cars with those numbers that are still as safe or safer than ever, and plenty good performing to boot (electric motors have tons of power).
