I was driving today on autopilot in the right lane and approaching was a car on the ramp.. My Model Y slowed down (not aggressively) so I though it was a phantom braking incident but looked over and noticed the car getting on slightly in front of me had its signal flashing.. Once the car merged in front of me normal acceleration resumed... I am impressed by the action of the autopilot predicting the car merge....These cars on autopilot are amazing...I drove some legacy EV cars and can say Tesla tech is light years ahead.
