If I may take the liberty of quoting some sentences from that blog: "They are in the womb of automotive expectedness – the ICE world of the last few decades – and in a span of about 60 seconds (approach car, beautiful, handles extend, OMG, get in, stunning, flat screen stares at them, panoroof slider bar, foot on break, speedometer flips over, roll away silently, first straightaway punch it, memories of first rollercoaster ride, fat-ass grins all over faces) they are shot out the birth canal into the bright light of a new, awesome world..."
Nicely put. I experienced the same reactions when I gave some of my neighbors rides in late 2013 when my S was new.
And yet...there are just as many people who are remarkably uninterested in Teslas. I can't really explain it or understand it. I have a neighbor, really great guy, in a tech field, who despite numerous invitations from me to take a ride in my S has never done so. His 20 year old son also has expressed no interest at all in the car. Another neighbor who has a top management position in a world famous high tech company, after getting a ride in the car, expressed polite appreciation but was not particularly excited. He had just bought an Audi a few months earlier.
In contrast, a neighbor who also works for that world famous high tech company loves EVs, has an Audi and was waiting for Audi to make an EV, got tired of waiting and last year bought an early 2015 Model S CPO car. He loves it. A few weeks after he bought it Autopilot V1 was released and he was blown away as to how his amazing new car was suddenly even more awesome.
So my experience is a wide range of reactions to the S, from raving enthusiasm to indifference. It's not just because where I live -- SF Bay Area -- Teslas are relatively common. It's because a large proportion of the car-owning population doesn't give much thought to cars, sustainable energy, technology, climate change, etc. A car is an appliance that gets them from A to B. That's it.
