Hi, from time to time I see this in the log files: Attention: Tile contains both drive-on-left (1) and drive-on-right roads (15389) The one "drive-on-left" road is clearly a bug in the OSM data. But finding that is pretty hard (I found one once by accident ...). I wanted to try to implement this myself, but I currently don't see that I have the time to dig into the code myself, that's why I write here my idea: Could we add an option (--x-report-wrong-direction or something similar), and if drive-on=left or drive-on=right is set, write the roads with the wrong direction into the log file? If drive-on= isn't set at all or to "detect", nothing should be written. So, additonal to increasing the counter, write the ID at that time to the log, too.
