As outlandish as this article may seem, I've seen seven different Model S Teslas in my 'hood (Santa Monica/Venice/MDR) in the last four days (five in a 24-hour period). While I didn't consciously count other brand new (plateless) luxury sedans, I can safely say that these Teslas represented a good portion of such cars that I saw over that period. Happy and bummed about this at the same time. Happy that Tesla is gaining ground in this area; sad that mine will be old hat by the time it's delivered.
