Years ago (maybe still) Microsoft had a research facility for self-driving infrastructure. Instead of putting all the recognition and awareness in the car itself, a lot of it was offloaded the mini city they built. Streets and stop signs with embedded RFID, etc.
This, of course, doesn’t stop pedestrians from dying. But I thought it was a cool approach to the problem to “update the world” instead of trying to make a product that navigates our unmodernized infrastructure
