No we're not!
In almost three years, I have only seen three unique Teslas that were not my own here in Virginia.
I just got back from a week-long trip to Vegas. I stayed at the Bellagio, and while I saw a gray Model S parked there one day, I didn't see another Tesla the entire week, despite looking for them while walking up and down the strip many times.
(I was surprised that S's still seem fairly rare, even on the strip in Vegas!)
