At $8500, I could justify having a 77 mile range electric car with a top speed of 30ish mph. That would take care of every in-town trip, but I couldn't do a full commute to work with it because the most sensible way of doing that involves a highway. If it could manage 50mph for 15 minutes, it could go on the highway and I could recharge at or near the office.

The cheapest EV currently available in the US is the Chevy Bolt, at $29000, about three times the price. A Bolt has four times the range, but still not quite enough to go one way on my most frequent "long drive".
