Re: Zebra crossings
Human drivers are hopeless at that.
We have a bus station where I occasionally wait for a bus. Sometimes - typically if needing to get upwind of a smoker, though perhaps also to watch for the bus - I'll wander out to the pavement in front. As soon as I do that, I'm near a zebra. I can be leaning on the railings and obviously going nowhere, but still most of the cars slow right down as if to let me cross. I find myself walking away from my preferred spot simply to get away from the crossing and stop them doing that!
I rather suspect an AI driver might do rather better than the average human at detecting a human who is not interested in crossing the road.
