Downtown city driving is certainly a high bar. Even veteran taxi drivers make mistakes or bad decisions when choosing a route. But certainly it seems like a a solvable problem, given that most apps/GPS units can track, and aggregate data to find the optimal route. I was impressed on my trip that Google Maps actually recommended alternate routes (on the fly), with time estimates based on traffic. I was able to cut off a dozen or so minutes based on it's suggestions. Also very impressed with the foresight that an app like Waze offers. During my 8 hour trip I navigated for 4-6 hours and was easily able to warn my driver about hazards (cops, wind, accidents, construction). The kicker is that Waze is "powered" by human reporting - which suggests the ideal solution is a hybrid of sorts.
