I've owned my MS for a year and a half and have absolutely loved the car, but something happened a few weeks ago that really rattled my confidence in Tesla. While I was driving on the freeway in stop-and-go traffic on a gray, rainy day, an armored truck slowly moves into my lane, and my car smacks right into the back of the truck at 23 MPH while on Autopilot (AP1). It was all captured on my dashcam. Since I was behind the wheel, I take responsibility for the accident. However, Autopilot clearly failed to see the truck in a scenario that happens dozens of times per trip (vehicle moving into your lane). On a lark, I pinged some random Tesla execs with the video via Linkedin to see what they think. A few days later, I get a call from my local service manager from Tesla Costa Mesa. He told me that they had pulled the data from my car over the air, analyzed the information, and concluded that: A) my car was on Autopilot when the accident occurred; B) the software and hardware performed within specs and as designed; and C) the reason the accident occurred is because Autopilot is not reliable in rainy conditions. That last sentence absolutely blew my mind. Autopilot may fail to see a very large truck in broad daylight if it's raining? What do you guys think?
