Mercedes-Benz previews its operating system MB.OS

Some Mercedes also have the bug where the sign classifiers somewhat regularly mis-read 80 as 60 for speed limits, causing cruise control to arbitrarily slam on the brakes in some parts of the country. You would think that they would catch these things with rudimentary quality control.

The automotive code for many of these systems is incomprehensibly awful but the entire process of how it is made virtually guarantees this outcome.

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.

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

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.

I just borrowed a Tesla Model 3 that stopped for green lights. I asked a service person: apparently it is known to stop for a green light if there is no car ahead. The display shows a green light, a red line, and fine print saying that the car will stop for traffic control.

I don't understand this. What does stop for a green light mean?

It treats a green light like a stop sign

Great way to get rear ended.
