I recently also tested such "feature" in a car from 2016, and I was quite unimpressed. As you say it has a lot of miss-identifications such as signs, and it doesn't work at all in mist, but for me it also failed several times to even recognize cars and blinded a few. For now it seems more like an technical interesting concept than a feature. I do not like false negatives in an technology that could cause result in car accidents. The speed limit sign detection is more useful as the false positives and false negatives is noticeable but mostly harmless.
