I hypermile my Volt every day, and I hypermiled a couple of Insights and a Festiva for years before the Volt, but I don't do it at the expense of all the other drivers around me. And I'll be the first to admit that I'm not above going around somebody doing 10 mph under the speed limit with cars piling up behind them.
I squeeze every mile I can out of my daily EV charge while maintaining enough speed to be as courteous as possible to the drivers around me, and I do very well without making a bad name for hypermilers
