Does anybody have insight on this? I love the fact that TACC, determined by geocoded speed limit, can be overridden. I am shocked just how lackadaisically some jurisdictions code their streets and highways. So I believe there are two principal reasons for overriding: 1) The speed limit is properly coded but is laughably lower that prevailing traffic. 2) The speed limit is improperly coded as in coded for 30 in a 50 zone or coded for 50 in a 30 zone. What I have found is it is virtually impossible for me to get it to work right. What I'd like to see is overriding is only in force until the next geocoding is sensed which resets the speed to the new, presumably correct, speed limit. I believe it is safe on the high side in that the speed is limited to 5 mph over geocoded speed limit. It's on the other side where I perhaps had overridden the speed limit and the speed limit goes up but the car maintains to lower speed. This forces the driver to constantly be adjusting the override speed. What would be nice, maybe it exists, is to tell TACC override value is zero. What's troublesome is one would think setting the override to be the speed limit should accomplish that but that is the root of this problem. Maybe it would be better if the override value dialed in is +/- some number where zero would be no override. It used to work better. I believe a recent update 'broke' it. Any thoughts?
