Me: Driving with my son in my silver Model S 85D, around 5:30 this afternoon, going on Lafayette surface streets from home to his swim school. You: Driving your brand new, post-refresh Model S 70, black, no license plates. Approaching from behind us at well over the speed limit, and then you suddenly decided to hold formation with me. You might not be familiar with the Model S's blind spots, but you were hanging out in mine, and that's why I was twisting around in my seat trying to see where you disappeared to. Then you did a great job weaving around cars (including me twice) as we went into the downtown district. My son and I were flabbergasted at how much effort you were going through just to gain a couple carlengths in stop-and-go traffic. We liked the part where you almost cut right in front of us, as we and all the cars around us were slowing for a stoplight, for no apparent reason. And it looks like your DS neglected to mention that the Model S comes with fully functional turn signals. All this happened within the space of about a mile. Welcome to the Tesla family. Now please learn to drive competently, before you kill or hurt someone. Thank you very much. Bruce.
