Right, and Tesla's messaging is not about efficiency. Their messaging has overwhelmingly been "holy shit this thing is fast! And green! And exclusive and the crowning achievement of our conquering of science and technology!"
Which isn't that different from traditional sports car marketing, except the green part.
Getting people to be more efficient does not necessarily mean selling efficiency to them and rallying them around it. CFLs and energy-efficient lighting has essentially become commonly as a fashion, as opposed to any significant increase in people's desire to be green. But I couldn't care less - if people are installing CFLs in their homes I don't really care how much they care about their electrical footprint.
I don't think fashion was a big contributor to early adoption. It was mainly the perception of saved money and frustration. Early CFL packaging often had a comparison chart showing the $30 you'd save on electricity versus using incandescent bulbs, and the 6-10 fewer times you'd have to change a burned out bulb over the next 3-5 years. It's not specifically that people care about "being green", but they do care about saving money and effort.
The market likely maps onto the technology adoption life cycle, and the hardcore SUV petrolheads are likely the 'late majority' or 'laggards'. That leaves a lot of room for market development before even considering those people. They'll take years or decades to change, so ignore them and focus on the customers in the early majority. That includes SUV or sportscar drivers who would like to save money, who do care about the environment, who have moved to a city, etc.
Have you even noticed how many hybrid SUVs are on the market? Who do you think is buying them?
I disagree. SUVs are a very common commodity in America, and there are many people whom acquired them for various practical reasons. I've had the same compact SUV since high school, over 10 years, and would love to 'upgrade' to an energy efficient electric car, I just can't afford it now, or any other car at this point in my career. Although I dream of the Model X, and think it's a great idea. I would rather take a train everywhere, but given America's infrastructure, currently a Model X is the next best thing.
