We worked with Polis, an open-source system. When Uber came to Taiwan that year, many people are very afraid they would take the job of taxis, that this algorithmic dispatch is going to ignore the professional driver license system, and people would get maybe higher quality service, maybe lower quality service, really nobody knows. And we use the Polis system to basically ask the entire society ‘what do you feel about this situation?’ Because people are experts in their feelings.
