motivation for VUS is to reduce inequality -- affluent neighborhoods make more notifications and are better served as a result
vehicles need to be distributed equally, though
contestability might counteract unequal distribution of vehicles, but it might also reintroduce previous inequality of affluent citizens posting more notifications
distinction between VUS that is tied to individual decisions and that is used for maintanence of public space
risk of VUS for maintenance is that it transitions into one for enforcement and individual punishment
VUS that does not process personal data can still lead to individual impacts -- e.g. enforcement uses data from VUS to go where the odds of catching someone in the act is highest
challenge for contestability is sufficient understanding of IT systems (technological complexity) (also e.g. with national representatives of the people)
those with know-how and legal clout can shape debate around tech systems
fundamental AI research is open, which aids supervision, but application of AI less so
external review requires expertise as well, hiring people is hard
focus of external auditors tends to be legal
