This is specific to France. I was driving back home last night and the part of the motorway was closed for repairs. This was planned well ahead and shown on the warning shields several weeks ago. The planned closure was between 21:00 - 6:00 every night, except for the weekends. Google and Waze new about it, Apple Maps did not. 🤷🏻♂️
I guess that there is not enough iPhone users around to feed the traffic data? If this is the case, however, I think Apple should team up with some other real-time traffic flow analysis services, else it really sabotages AM routing experience.
