Anybody have any details on the Highway Set Speed Auto Change function? Seems to work well on the interstate, but the preset speeds are wack-a-doo! If the interstate speed is 60, the car sets at 62. Other presets are 50~50, 65~65, 70~71, 75~75. I don’t understand why some are exactly the speed limit and some are a little higher. Is this something I can set myself? The dealer doesn’t seem to understand what I’m talking about. Lol.

That's interesting. When I'm in SCC, if I have it set to the speed limit, it changes automatically with changing speed limits. And it's exact. If it's a 70 MPH speed limit, the car sets to 70 MPH. I've never seen it set to 62 or some odd speed like that.

The only odd thing to me is that this only works if you first set the car to the current speed limit. If I'm in a 60 MPH zone, and the car's set to, say, 59 MPH, then it doesn't follow the changing speed limits. I haven't noticed any options for that. It's probably time for me to read the manuals again. I did that once when the car was new, but there's too much to remember it all.

I did a manual deep dive but didn’t come up with any additional info. :/

My 2018 G80 has the beta version of SCC. Eyes see speed limit sign and sends signal to foot operating throttle or finger to adjust cruise control speed. It's fairly accurate but occasionally doesn't' adjust the speed. I've got the paperwork (speeding tickets) to prove it.
