This is what is keeping my wife and I from getting her a Nissan Leaf. She drove a Nissan Versa (basically the same platform but traditional gas engine) until she was hit by another car. The accident was caused by a person in the oncoming lane not seeing her and turning left, striking her driver's side door. The other person was in a mid sized SUV (first gen Jeep Liberty) and was only going about 15MPH when she struck my wife's car, but the force pushed my wife's driver side door all the way into her seat and against her hip. The Versa was severely frame damaged and not driveable; the only damage the Jeep sustained was losing the bumper cover.
Thankfully my wife was not hurt apart from some bruising and soreness on her hip, but if the other car had been going faster (say, at an intersection) she could have been seriously hurt or killed. She is now driving our Crown Victoria, a full frame vehicle with five star crash ratings all around and reinforced doors due to being a former detective's car. Her fuel economy sucks, and she was just moved to a more remote office at her job which makes the Vic a very expensive commuter car now, but we're leery of getting her a subcompact (gas, hybrid, or electric). It's probably an irrational fear; such an accident is probably a once in a lifetime thing, but traffic is insane where we live and work so we both feel much safer with her in "The Tank".
