The PiP only has 11 to 15 miles of electric range. Yet even this short distance can move one-third or more of a typical driver's miles to be electrically powered when it is plugged in regularly.
So maybe a low-speed vehicle or a PHEV with a short electric range would not work well for you, that does not mean there is no one that could use this vehicle. The more options there are in the market, the more people can get behind the wheel of a plug-in vehicle.
So next time you are tempted to attack this or that type of plug-in vehicle, stop and ask yourself, is it better than an internal combustion vehicle. The circular firing squad needs to turn around and know that the other plug-in drivers have their back. There are plenty of other targets for your rage. When all cars on the road plug in, then you can start worrying about which ones use too much gasoline. Until that time, let's try to get more cars to plug in. The perfect should not be the enemy of the good.
As much as I'd like to claim I am completely above this fray, I have serious issues with hydrogen vehicles, but that is a post for another day.
