  It's not trivial from first principles, but traffic sign recognition is more or less a solved problem at this point (production Teslas read speed limit signs as you drive by them, for example) so it would be trivial to implement given what's available now.

    Teslas being able to read a single format of signs is absolutely not indicative of their ability to read and recognize the hundreds of traffic signs in the US, many of which are located in non-standard positions. If traffic sign recognition really was a solved problem, every car manufacturer would have implemented it by now. If implementation really was trivial, we'd all be talking about which self-driving car we're going to buy this year, not when the first self-driving car might become available.

      I've seen it in action in other contexts on all sorts of different signs. And for alerting a driver who's failing to stop at a stop sign, all you have to look for is one kind of sign that's even easier to recognize than speed limit signs: just look for a red octagon, and no need to OCR the text.
