With the new update, 2022.20.6 and .7, the car misses a lot of obvious speed limit signs. This is on rural 2 lane highways in Colorado. As a result, autopilot will often restrict me to going 50-60 in 65 zone. This makes autopilot useless....! I note that Google Maps is giving me the correct speed limit. I also note that Tesla changes what it thinks the speed limit is even when there is no sign. So it must be using a database, which is pretty bad! Sigh.
