My '18 AWD with HW 2.5 got the 12.5 update last night. I drove it to do a food run around lunch time today, and found
1. I saw cones!! Alas, in the instances that I caught them (with the corner of my right eye), they didn't match physical cones or even any hazard that's visible to my naked eyes.
2. It phantom-braked when encountering overpasses on highway. I have never experienced this before. The brakes weren't sudden or jerky, more of a steady, significant speed drop-- from 75mph to 50mph.
BTW, I got the navigation update right after the firmware update. I wonder if issue #2 is related to the new firmware or the new navigation update. Anybody has any insight?
