Heads-up Display

Has anyone experience a incorrect speed limit display. I was driving a a street and on the HUD, it displayed a 40 limit when it should have read 30. See pics.

That happens frequently in any car. GPS sometimes can’t pinpoint exactly where you are (weather, buildings), when the speed changes, what the speed limit used to be (encoded in the map). When you get pulled over I’m pretty sure the officer won’t take the “but my car said” as a valid excuse.

Sometimes it will read 35 as 85 and the car will accelerate. Not fun when exiting a highway that has a curve marked 35.

The car also reads signs to report the speed limit maybe cleaning the camera might help or a software issue to be fixed?

Perhaps try turning off cruise control when you're exiting the highway. Actually drive the car like you're supposed to 🤦

Once you pass that sign you should see a second speed limit show up. It shows up but even if you tell the cruise to follow the speed limit it won't in special speed zones.
