I have a brand new CR-V. These cars have been able to 'read' the speed limit signs for a handful of years now.

It read a 25 Mph sign as 50 Mph in my neighborhood the other day.

I also previously had a CR-V and in one section of road on a curve, where the fog line isn't clear and there is a chip-and-seal fix going across the roadway, the lane keeping assistant complains about drift. The new one does this, too. Same place.

I've encountered similar issues with the braking warning.

These camera-based systems are imperfect. Humans are also imperfect, but unlike cameras, some of us have some power of deduction/reasoning/thought.

If anything, I would prefer California's approach where the car complains at you if you're going >10 Mph. Since CA is adopting that rule in the coming years, I'm sure we'll see this on all cars in the US (2030, I think?).

I do wonder for those people who enjoy track meets with road-legal cars will handle this technology.

EDIT: What happens if the user blinds the camera? It said it also uses SatNav, but that's not perfect, either.
