Consumer Description

On at least three (3) separate occasions, my Tesla has automatically slammed on the brakes. Once it happened while driving on Hwy 101 in high speed traffic flow. I was passing a right side on-ramp and I believe the Tesla got confused when it saw a car approaching the highway from the merge lane on my right. One time it happened on Hwy 101 in a construction zone marked 55mph. Perhaps the auto drive cameras got confused by the poorly marked road and lack of lane markings as traffic merged. One of the times it happened in Santa Barbara on State St, in a 35 mph zone. In each of the above cases, *I was not in autodrive*. I was subscribed to Beta software updates, but after these scary incidents, I discontinued Beta and went back to Standard updates.
