Since we are now talking about the appearances of Model S'es, here is what I see in the San Francisco Bay Area.
I live in a town called Atherton in the Bay Area, it's a pretty nice neighborhood. Model S'es started to pop up around here about 6 months ago, before TSLA's epic run. At that time, I'd see about one or two Model S'es a day. Now a days I'd see about three or four a day. And yesterday, I had to drive on the crowded 101 Freeway during traffic hours. In the matter of 20 minutes, I saw about 10 Model S'es on the HOA lane in the opposite direction. They are everywhere now.
Another observation is that where I work in the South Bay (Cupertino to be exact), Model S'es are pretty rare. My company has plenty of charging stations for electric cars, but they are mostly taken by the Leaf's, the Volt's, but not Model S'es. Seems that Model S'es are still out of reach for the masses. After all, it's $100K.
In any case, I'd imagine there are still a lot of rich people out there that have not heard of Tesla. Still a big market out there for the Model S (and later the Model X). The better days for Tesla are still ahead.
One more thing. A good friend just bought one: P85+. When TSLA was below $40, he margined his account pretty heavily, sold it all at $130, bought a Model S. Boy, that thing was wonderful to drive (he let me have a go). For those of you that have one already, you have a great car!
Good luck to all.
