Until a few days ago, my MS seemed to know that the speed limit on a local freeway was 65 without having to read a speed limit sign. While still on an on-ramp, the TACC default would become 76 -- I have the Speed Assist set to relative +11 (10 over + 1 for speedometer error adjustment). I don't specifically recall whether the speed limit showed as 65, but I'm sure about the TACC default. Now, on the on-ramp and on the freeway until a speed limit sign is seen, the TACC default and the speed limit remain blank, and engaging TACC causes it to set to whatever speed I'm currently driving. It's only a minor inconvenience, but I'm curious as to what may have changed. The car's been running 2.28.19 for almost two months.
