I know that the latest feature rollout had something to do with detecting emergency vehicles - but the other day I was driving at night. I was on FSD Beta, going 69 in a 60. There was a cop pulled over up ahead with his lights flashing. My Tesla proceeded to slow down all the way to 60 as it passed. I couldn't tell if that was a consequence of a vehicle being detected on the side of the road and the tesla slowing down as a caution or if it was recognizing a police car and slowing down to match speed limit. Thoughts?
