Wapo journalist verifies that robotaxis fail to stop for pedestrians in marked crosswalk 7 out of 10 times. Waymo admitted that it follows “social norms” rather than laws.
The reason is likely to compete with Uber, 🤦

Most walkways are marked. The vehicle is able to identify obstructions in the road and things on the side of the road that are moving towards the road just like cross street traffic.
If (thing) is crossing the street then stop. If (thing) is stationary near a marked crosswalk, stop and go if they don’t move in (x) seconds. If they don’t move in a reasonable amount of time, then go.
You know, the same way people are supposed to handle the same situation.
Most crosswalks in the US are not marked, and in all places I’m familiar with vehicles must stop or yield to pedestrians at unmarked crosswalks.
At unmarked crosswalks and marked but uncontrolled crosswalks we have to handle the situation with social cues about which direction the pedestrian wants to cross the street/road/highway and if they will feel safer crossing the road after a vehicle has passed than before (almost always for homeless pedestrians and frequently for pedestrians in moderate traffic).
If waymo can’t figure out if something intends or is likely to enter the highway they can’t drive a car. Those can be people at crosswalks, people crossing at places other than crosswalks, blind pedestrians crossing anywhere, deaf and blind pedestrians crossing even at controlled intersections, kids or wildlife or livestock running toward the road, etc.
Thing? Like a garbage bin? Or a sign?
Person, dog, cat, rolling cart, bicycle, etc.
If the car is smart enough to recognize a stationary atop sign then it should be able to ignore a permantly mounted crosswalk sign or indicator light at a crosswalk and exclude those from things that might move into the street. Or it could just stop and wait a couple seconds if it isn’t sure.
A woman was killed by a self driving car because she walked her bicycle across the road. The car hadn’t been programmed to understand what a person walking a bicycle is. Its AI switched between classifying her as a pedestrian, cyclist, and “unknown”. It couldn’t tell whether to slow down, and then it hit her. The engineers forgot to add a category, and someone died.
It shouldn’t even matter what category things are when they are on the road. If anything larger than gravel is in the road the car should stop.
