I agree with your points. The average buyer rarely drives more than 40-50 miles a day anyway and many families own a second car which is perfect for longer trips.
Arguing that electrics suck because they can't go 250 miles on a charge and charge in 5 minutes is like arguing that you "need" to drive a pickup that gets 15 mpg because you haul sh!t home from the lumber yard once or twice a year. People being afraid of change is what it usually boils down to. I'm a big proponent of people doing what they want (driving something with crappy gas mileage if that's what makes them happy) just don't complain when gas hits $6+ a gallon in a few years and the people with electrics aren't paying hundreds a month to fuel their ride.
In fact for many people with a typical commute an electric is actually more convenient because you "fuel up" over night, in your own garage. No side trips to the gas station.
