Yes the corner cases for automated bus driving are pretty unique, and require some mix of situational awareness, empathy and aggressiveness. No way we can see this fully automated in next 20 years in regulated markets like most of Europe. Buses are some of the most aggressive traffic participants in order to get folks where needed without frequent massive delays.
What can work is to have some HQ team of 5 people managing say 50 buses, stepping in in complex situations. And seeing this team being used less and less over time without affecting incident rate negatively. But internet connection would have to be absolutely perfect, I mean 100%, can't have a bus full of folks stuck in some signal-less tunnel.
