Phantom slowdown doesn’t really happen anymore. I primarily don’t do it because of the stop sign issue and sometime some turn signaling without changing lanes.

So basically… embarrassment. I don’t mind it driving like an old person, but I’m embarrassed to be seen as driving that way.

Maybe due to Phantom breaking? that's the #1 issue I've seen with Enhanced Autopilot and it's terrifying when it happens.

I've never had issues with lane changes or general driving, but the phantom breaking (where the car slams the breaks out of the blue) is extremely unnerving, and the main reason why I use self driving a less these days than I did in the beginning.
