It probably goes without saying that Tesla’s are EVERYWHERE in the Bay Area. I can’t count the number of S and X I see each and every day (hundred?). I only count Model 3s now. On average I see one a day these days (January 2018). But sometimes it’s still crazy how many I see. Last weekend, I saw 3 (one blue, one silver, one white) within 10 minutes of each other on the road “in the wild” (not counting the ones that are now in the Stanford and Santana Row stores).
I tend to only notice the number of S and X in certain situations like
@mkspeedr was mentioning. Last being a few days ago when I was transitioning from I-880 to 280 N and noticed that of the 4 cars on the sweeping clover leaf on-ramp at that exact moment, 3 of them were Teslas. Model S #1, some ICE car, Model S#2 and my Model S. It’s moments like that where it’s reinforced just how many Teslas are around here.
