Don't see any problem.

But Tesla should program the speed limit as the street posted limit if no car in front of you or the speed of car in front of you. This is how human drives.

No what I am saying is the speed limit shows on the screen as 55MPH as the posted speed limit. I am driving 70 in a 65MPH zone and this just started after the most recent update. Before it showed the correct posted speed limit as 65MPH.

I have noticed this as well in my M3P, posted limit goes from 55 to 65, I’m the only car on the road and it stays 55. Clear 65 signs on both sides of the road also. I can / have to force it up to my speed 72 via the wheel dial.

Has anyone with this issue tried a hard reset to see if it fixes the problem?

That specific statement sounds like a bug that's been around with FSD for a few months now. It just can't read 65 mph signs. If you watch the visualizations, it won't even show the sign.

I had the same problem multiple times in Florida: does not detect 65, keeps 55 only.

I also have the problem where it interprets the "Florida State route 60" sign as a 60 mph limit.
