I just ran into this issue in Montana the other day. Weird thing was that it’d sometimes read the 80 mph limit correctly, then a second or two later revert to 60. My Sprinter just beeps at me, though. No brake action if it thinks I’m speeding.

Everyone I know that has discovered this bug, discovered it in Montana. All of the States that have ubiquitous 80 mph speed limits are clustered around that area.

It reportedly happens with 80 kph speed limit signs in Canada as well.

Texas has an 80 mph limit on a long stretch of I-10. They have one other highway (130) with an 85 mph limit.

Wonder if the “80” is from maps, which is then overridden by buggy vision?

80 mp/h speed limit?!?
