I have a 2016.5 S P100D with FSD. And until last month or 2, it recognized all stop signs and stop lights and reacted appropriately. Recently it doesn't see the stop signs until just before I get to them, and then just flashes and hits the brakes and runs the stop sign. I have taken it to TSS and they said it's working fine, because they tested it on a low speed city street setting, but higher speeds (say 45 mph+) it is absolutely horrible. Does anyone have any idea what is going on? It still recognizes the stop lights from 600+ ft away and stops fine at those. Thanks for your help!
