This was a fun read, but unfortunately, the electric car isn't practical yet in the environment it should excel the most at - the city. It's only a feasible option if you're a home owner with a garage. I could totally afford a tesla, and I love them, but I don't want to own anything beyond a condo in the city, and that means street parking. Even in the best neighborhoods where I wouldn't worry about the car getting stolen/vandalized, there's still no where to charge it! Residential city areas are never going to be lined with charger plugs for people to parallel park outside their apartments and use.
So, the only people it's practical for, are suburban (or very well off urban) people who don't drive often. I just don't see the infrastructure needed happening in a city the size of Chicago within my lifetime, and since populations are still centered there, I don't see gas cars going away in my lifetime, as much as I'd love them to.
