a) Most humans aren't aware of these things, either, so they're really non sequiturs at best. b) Even if you accept them as valid premises, it's much easier to disperse this kind of info to every car on the road than it is to disperse it to humans (every tourist in a city needs to know where every bar / park is? Or watch the local news?)

Those were all real examples. These kinds of things happen in my area every day, and drivers are actively taught to look for signs like these before they are allowed to qualify and drive independently. Obviously not everyone gets the message, and the best anticipation skills only develop with more experience, but nothing I described was unusual or exceptional (other than the last one, which was quite a specific example of a more general idea).

On your second point, the important thing here is that you don't need to disperse much of this information to humans. Humans automatically recognise situations based on all of their experience, not just their driving experience. Of course sometimes external information sources like the news might be helpful, but much of it is just down to understanding context. See fresh horse crap on a country road? Someone's probably riding horses nearby. Horses scare easily. So, slow down and try to avoid anything noisy that could startle the animals. How many of today's self-driving algorithms take into account this kind of implied knowledge?
