On the other hand, my parents live only 90 miles away; my mother-in-law lives about 20 miles away, and my father-in-law lives 3,000 miles away -- I'm not driving to reach him. I think that people who have relatively routine commitments more than 250 miles away but less than 500 miles away are a small enough segment of the market that you could reasonably describe the market as "disrupted" if those people remained on gasoline cars and most other people went to electric. That said, I don't buy even a little bit that we're going to go from "no commercial versions of this technology at all" to "being produced in car-battery-sizes and gigantic numbers" in two or three years. If Li-ion batteries aren't good enough, then any electric car disruption is at least 5 years out.
