RE: Tesla's Model S will go 300 miles and cost $77,400
I attended a test-drive day with the Tesla folks and their "Sport" model. They had reasonable-sounding answers for every objection voiced above. Principal among the solutions was an agreement with one or another hotel chain who are already installing charging stations for the quicker-fill options. Tesla supplies a list of power points throughout California; otherwhere may not be as well-primed as California, although the demonstrators described cross-country trips and regular "commutes" between L.A. and the San Francisco area.
If you are interested, dig up the Tesla Web site. The Sport is quick, well-put-together, and impressive in just about every respect. Not real kind to taller people, but I reckon the "S" will handle that.
