If most users are connected to the same system, an obvious direction would be optimizing globally - if there are two routes to go, just load balance them. I live in Beijing and the traffic is horrible sometimes. The Uber counterpart Didi mandates the routes, and sometimes counterintuitively nice - it seems to be a detour in a narrow valley but it's faster because there is no traffic jam there. I'm not sure Uber or Didi is doing this already. At the end of the day, if most vehicles' GPS is connected to a single system, while the system is recommending routes to most users. Then it would be possible for the system to optimize for the whole population, rather than being greedy for individuals and create traffic problems.
