Unfortunately, you really can't solve these kinds of questions with the full on deterministic approach. The world is big, speed limits change, databases have to be updated.
Google maps was (dangerously in the winter) directing people to an old road, into mountains after a new one had been built. It took national news, and several months of attempts to get them to update it.
The just build a big very accurate database approach is the one I would absolutely guarantee will never work.
- rayiner 7y agoGoogle also for a long time didn’t properly account for Rock Creek Parkway in DC going from one-way south, to bidirectional, to one-way north depending on the time of day. Also, it still doesn’t realize that the street I live on is a pedestrian street with car barriers at every other intersection. (You have to drive down the correct subdivision road from the main road, instead of just getting into the subdivision and expecting to be able to drive down the pedestrian road to the right house.) So Uber drivers will constantly call me saying they are stuck and can’t figure out how to get to me house. (The road was turned into a pedestrian road maybe 5-7 years ago now.)
- londons_explore 7y agoRoads which have restrictions changing on a hourly/daily basis google doesn't understand, but there will be a warning in the directions ('this route contains private or restricted roads'). If there is something out of date, hit the report button and it's typically acknowledged immediately, confirmed in a few hours, and public within a few days.
- rayiner 7y agoGoogle recognizes it now, but it took years. (For a major thoroughfare in the nation’s capital.) Just reinforcing OP’s point that you can’t rely on the map being up to date.
