Version mkgmap-r4580 was committed by gerd on Fri, 18 Sep 2020 improve driving side detection (drivingSide.patch by Ticker Berkin, modified) Attached is a patch that doesn't assign a driving side to more types of ways where it is not relevant. This speeds up processing slightly and, in some circumstances, stop the warning: "Tile contains both drive-on-left (#) and drive-on-right roads (#)" Previously ferries were ignored, this patch additional ignores one-way roads and roads that don't allow motor vehicles (eg footpaths & cycleways) http://www.mkgmap.org.uk/websvn/revision.php?repname=mkgmap&rev=4580
