NOA - Speed Limit Changes

My Y (with FSD) does change the speed if the speed limit is lower.
AP is limited to 5 mph over the current speed. If I'm travelling at 55 mph with the speed limit of 50, as soon as it sees the 35 mph speed limit sign, it lowers my speed to 40 (35 + 5). I do not believe that it speeds back up when the limit goes back to 50 mph without manually intervention.

I also believe that if you are using just TACC and not AP, I do not think it slows down.
I just washed the car today (finally a day above 50 F) and it's clean, so do I really want to go test it and get the car dirty again...
Maybe tomorrow.

Thanks. Again, I only have Enhanced Auto Pilot. So, looks like you need FSD to get the speed to adjust downward automatically...

OK tested FSD today. You are limited to 5 mph over the speed limit.
When a new, lower speed limit appears, the car does slow down to 5 mph over the new speed limit.
When a new higher speed limit appears, the car does not increase the speed automatically.
