> lane markings are confusing but GPS and inertial readings should have clearly indicated that that is not a lane Aside from GPS’ accuracy as mentioned in other replies, also take into account the navigation’s map material. The individual lans are probably not individually tracked on the map, but a single track per road with meta data specifying the number of lanes amongst other featerus. So even if GPS would have provided very accurate position readings, the map source material might not even match that level of detail.
