    Of course, when approaching an octagonal stop sign, my Prius dash displays the same sign, STOP on a red octagonal shape.
    But I live in Ottawa, and noticed that when driving across the river in Quebec, the same shaped sign with "ARRÊT" is not recognized. Presumably, if I were using the French dashboard, the reverse would occur.
    Which leads to the following thoughts:
    1. Clearly the car is matching an image of STOP with what it sees. But in Quebec, stop signs can either have "STOP", "ARRÊT", or both. So what does the French dash do?
    2. Canadian provinces use the "Manual of Uniform Traffic Control Devices" in traffic signage. So why doesn't Toyota allow the car to recognize all of them, or the more important ones?

    Mine only rarely detects a stop sign. Of course I know that the driver is required to pay attention at all times.

    Is that really a function of the cameras on the car, or GPS mapping software that's being used?

    The camera is helpful at times. It always seems to get the speed limit right. But it also can cause a dangerous dependency on it. The other day, I was cruising along, allowing myself to take my eyes off the road, trusting the driver assist, but when I looked up, I saw a vehicle ahead of me that had pulled over to the side, There was no shoulder, so I would have hit it if I hadn't seen it. There was no indication of any collision avoidance, so I likely would have hit it head-on.

    I'm admitting my mistake, so before you condemn me for it, showing your lack of character, just understand that it was a lesson well learned on my part.
