In my opinion, a completely electric car may be okay as a second car, to be used for local runs of short mileage. I would have serious reservations, however, about buying one as a daily driver for a 75 mile round trip commute each day. Given the limited range between recharging, what happens if you get stuck in a traffic jam for an extended period of time?
We have chargers at work. Co-worker of mine was stuck in traffic for 4 hours, and had a good 40 miles or so left by the time they got home. The key is to have a charging station at work.
