Sorry, but as someone who has a Roadster and also an order for a Fisker, I take exception to your characterization that a Karma customer does not "cares that much about consumption or they would go for the Model S." I don't take personal offense, ;-) more an offense to the masses who believe that it is all EV or nothing. It's dangerous to think that you can convince the masses to wean off their addiction to foreign oil by going from an all ICE car to an EV without any steps in between. The Prius took the football down the field after the EV-1 did not make believers out of everyone. The PHEVs will take the ball down the field even more, 'teaching' people how simple it is to plug a car in without giving them the range anxiety (GM lawyers... am I allowed to say that?) until they get over that fear. The Fisker will bring PHEVs down field by making it sexy and luxurious to own & use a PHEV. All of these steps serve to convert people slowly but surely.
The problem will be if one of these conversion processes goes awry. There are PHEVs and EVs coming to market in the next 12 months that if they even have a hiccup will be labeled by some as a failure which will trickle down to the masses as telling them to stay away from EVs. My friend who has a Lambo was one of the 1st to point fingers at some of my Tesla service tales of woe, telling me that is why he would not buy a car from a start-up, yet he completely ignored the fact that for nearly a year he was telling me tales of woe about the Lamborghini dealership service not being able to fix his engine grinding for nearly a year! Perception is reality to some! The EV community should be a 'big tent' group and realize that there are 31 flavors of ice-cream and that we need the variation of flavors to score a touch down for the EV!
