Hi,
occasionally on the autobahn I encounter a lane assistant that gives faulty info, most notably one that now, with HD Traffic, I encounter every morning on my way to work: travelling north from Bonn along the A555, and then changing over (at the Köln Süd intersection) to the A4 towards Aachen.
To do this you have to take the center lane, but Navigator shows the right hand one, which would also take you onto the A4, but going away from Aachen.
What infos does the lane assistant use to do its thing? Any general advice enabling me to correct OSM when I come across something like that would be appreciated.
