You're suggesting that self-driving cars may have to drive slowly and carefully in cities. I don't really see a problem with that. Pedestrians aren't frequently in the immediate vicinity of roads with limits higher than 35mph in my experience. Any human driver has to drive cautiously in the vicinity of pedestrians anyway, if they don't want to risk manslaughter. I'd want SDVs to do that too.

Slowly and carefully, yes. Assuming that any pedestrian could leap in front of your car in violation of traffic laws - no.

Where I live in California, there are two major streets with crosswalks in regular use, with speed limits of 40 mph or higher (and travel speeds of 50+ mph), within a quarter mile of my home.
