Honestly, small streets where there's really only one thing you can do (go straight forward but don't drive into anything) are not as hard as where cars are already driving today because the speeds are very low and the distances you have to consider are are pretty short. This is not like making unprotected lefts across 6 lanes of traffic in Beijing.

The hype around "full self driving" is exaggerated because today it's not even "limited self driving," let alone SOTA.

Did you ever drove through e.g. city centers in Europe or Asia?

There are not only missing lines but it's often also used by many people which walk on it. A self driving system doesn't only have to figure out where the steet ends and walkways begins but also has to correctly detect many moving people and animals.

Additionally, there are frequently side streets or walkways which are not mapped in every map database...

Yes. My point is that detecting people is not hard and everyone but Tesla already seems very good at it. What's hard is understanding what they want to do and reacting to it. That part is much easier if everything is going 10 mph or less.

Detecting inconspicuous transition between sidewalk and road is difficult, but if you haven't noticed, human drivers don't seem to care much about it either.
