Hopefully they will get UI data. Even the best of current generation of GPS are awful to use if you want to force it to take specific routes. Even analysing the route the GPS is building for you is not often easy and in any case a lot of the metadata is not available visually before the fact. For example, you will get the same symbol for a 4 lanes national road or a 2 lane one. No way to tell the difference on the map as they are the same road category, however, the GPS knows the difference ( it has lane information, different exit strategies, speed limitation difference, ...) but doesn&#x27;t display it.<p>When the car primary control is the GPS that better change.
