Beware construction zone speed limits

[Mr Sir]

Recently I went on a few thousand mile road trip. Unfortunately on supervised full self driving, my Beast continued at ninety miles an hour, with traffic including truckers, instead of slowing down to fifty five, as the signs instructed in the construction zone. It didn't bother me at all once I realized the camera didn't detect the change of speed limit. (Maybe since the signs are always orange instead of the usual black and white in the construction zones?)
Also, on self driving, I had to intervene a few times to avoid accidents. This is because our vehicles can not predict what other drivers are going to do apparently during certain circumstances. Specifically, when I saw a trucker pull in front of another trucker and hit his brakes, I knew the trucker behinds only move to avoid the accident was to swerve to the left which is where I was. I of course moved to the left as did the trucker avoiding the accident. I'm pretty confident that the trucker behind was very happy that I did this also since he had no realistic options.
This is just an example of why we must diligently stay awake so that our vehicles don't get any bad press or worse.

my CT pays no attention to construction zone speed limits, it sees them it just thinks they are not applicable. I scroll down to a reasonable speed. But generally the flow of traffic doesn't slow either unless you know who is parked along the road.

My CT rarely gets speed limits right. I'm in Canada. It sees "110" as "70" and then drives at 100. It sees "90" as "80". "50" as "30" and goes 57. Except with it thinks it's "20". I drove 3 hours on the highway and passed many 110 signs - dozens of them. It never got one correct. I'm working the speed wheel often while on FSD. It certainly doesn't understand other speed signs, like "30 when lights are flashing". But it seems the latest FSD either sees "No right turn on red" or has learned from my constant interventions at the particular intersection.

I had a similar situation but FSDS handled it before I could. When I realized a truck was moving into my lane I quickly checked my left mirror and before I could turn the squircle FSDS had already begun the move. I was VERY impressed.

I agree with the randomness of FSD with regard to speed limit signs. It understands normal signs about 75% of the time, and either disregards signs at other times, or selects random velocities to drive. I can't tell which. FSD puts me at high risk of speeding violations, since I am somewhat trusting of the AI when it is driving.
