This is a stupid question, but why would I buy a plug-in/hybrid that only goes 40 mi on battery only? Is the plug just for show to get the credit?

Wife has a Chevy volt with short commute so most days she's battery only and rarely needs to hit the pump.  When she is running on gas though it's efficient because the battery charges when idle and breaking and it seamlessly switches back and forth so the engine turns on and off or runs from both once you get a decent charge built up.
