This is one of the very things that hurts (or will hurt) Tesla's growth - everyone wanting to make the car 100% about the env. Look, not everyone has to be convinced about global warming for them to buy an EV. I had a friend over a few weeks ago who hates everything about the whole environment "religion" (as he calls it). He laughed at me for buying a Focus Electric (though I paid $13,500 for it brand new). I told him I wanted him to drive it and he agreed to. He was SHOCKED! He couldn't believe how good the car drove and how quick it was. Then I explained to him that a full charge costs me about 50 cents (in Georgia). He immediately asked if they made an small electric truck. He said he would go buy one TODAY. Even after I told him they didn't, he asked me to be on the look out for a Focus Electric for him to work.
So, you see, we need to stop trying to force anything about the environment on people in an effort to make them buy EVs. I mean, dang, even by your own admission, 50% of the population believes in it, yet, 99% of all cars are STILL ICE vehicles. So, my approach when I tell people about Tesla and EVs in general is to simply explain why, all things being equal, an electric car is MUCH better than an ICE car. In other words, without EVER considering the environment, people should still want to buy an EV. As long as Tesla, Musk, and Tesla's followers continue to use the climate angle to sell cars, 1/2 the population will simply say, "I don't even see the environmental wackos driving electric cars, why in God's earth would I want to drive one of the POS's just to help the environment?"
Climate change, the environment, pollution, etc, will NOT ever sell enough cars for Tesla to make it - as long as people THINK they are sacrificing or losing something by driving an EV. I mean, heck, truth be told, I know TONS of people that tell me they are environmentalists that say it's TOO much trouble to recycle ("when they make it easier, I'll do it."). So, do we REALLY expect people to make a [perceived] sacrifice in ANYWAY and drive an EV? No. But, if we (Tesla, Musk, and fans) sell the cars on their merit, and don't make it about a polarizing issue like climate change, the cars will sell - period.
