Some sort of "wow" development in the field of portable energy could change things but even having to plug in your car at all

You mean like a 90s battery swap that is faster than filling up your car?

Even without that, the battery has a range of 300 miles. Even when I commuted from West Virginia to Rockville every day my commute was only 120m round trip... Charging is free at Tesla superchargers, which are planned to cover 80% of the US population by 2014, and 98% by 2015.

is going to be a huge barrier to anyone not in a single family home, which, I think it's safe to say, will automatically exclude most people in America.

Well, the cars start at $62k, after federal tax credit, so I think it's safe to say it already excludes most people in America. But there is more than enough rich people worldwide to ensure very healthy sales growth.
