As inefficient as a gasmobile may be, when the gas gauge gets low, I can pull off the LIE at the next exit and fill up in less than five minutes. When the electric gauge nears empty, I'm pretty much screwed.
If your regular driving habits would leave you feeling anxious about a pure EV’s range, then consider an extended range EV like the Chevy Volt. Your first 40 miles every day are electric and you have a 340 mile gas tank waiting for you whenever you go farther. You would only notice that you have switched from electric to gasoline by the rumble of the engine.
That, and the impact on your wallet since electricity costs about half as much as gasoline on a per-mile basis.
