Just ranting here - The psychological disconnect between a remote operator and passengers in a robotaxi needs more research though. Remote operator might have less empathy and responsibility towards passengers possibly causing moral disengagement. The remote driver might never face the real-world aftermath of their actions, which can reduce their sense of remorse or responsibility. There could be complex legal dilemmas too (especially if operator is from a different country)

But this has definitely been researched a lot in the field of military drone operators who can make life altering decisions from thousands of miles away.
