I can get about that on a tank of gas in my cmax. I wouldn't drive it non stop, but it means I can fill up before a long (for me) trip, drive a few hours, stop for food and restrooms, and drive on to my destination without stopping for gas. If it's not that long, I may be able to drive back too, without filling up.

If there's a charger close enough to a restaurant you'll eat at, that sounds convenient, and I've seen a lot more chargers on my long distance drives... but usually not at the restaurants I want to go to.
