I don't think anyone has mentioned this yet. I received firmware 2018.49.20 a few days ago and at first did not notice anything different. However, the first time I used Navigate on Autopilot I noticed that now, after passing a slow car by moving into the high speed lane, the car will ask for confirmation to return to a right hand lane. I think this is new behavior with this version of firmware; at least I had not noticed it before with 2018.48.12. I think it's a welcome improvement and a move in the right direction. However, I found the prompts to return to the right hand lane to be too aggressive. On numerous occasions the car would insist I move to the right and as soon as I complied it would then want to go right back to the passing lane because there were still slow cars in the slow lane. It's a needed improvement, but it could still use some tweaking. Anybody else notice this change?
