Apparently, Russia had left-hand traffic until the very ending of the Tzar's rule. This is according to a Dec 25, 1986 - Jan 1, 1987 article of New Scientist magazine entitled "Left is right on the road" by Mick Hamer. CKBrown1000 talk 07:45, 24 April 2011 (UTC)
Nigeria used to drive on the left but now drives on the right. Could the author of the map take this into account? Regards.
Also, the article states the same for Portugal —Preceding unsigned comment added by 131.107.0.111 (talk) 08:21, 25 August 2009 (UTC)
The date for the switch-over in Paraguay has been found. . Could someone change the colour of that country from red to orange, please. --Andhanq (talk) 22:34, 23 June 2011 (UTC)
Hi. I'm just wondering what is the RS backing up all the green colours, that supposedly "had different rules of the road (depending on one's location)", e.g. Canada, China, Spain, Ukraine, etc... I'd like to look into the specifics of how it worked, but don't know where to start. -- Jokes Free4Me (talk) 12:29, 12 May 2013 (UTC)
The United states is all orange? A bit simplistic and hard to believe: Alaska used to drive on the left, now drives on the right? Since when? Also, would not the Louisiana Purchase have followed France's lead? Also New France, essentially that portion of the US west of the Appalachians? — Preceding unsigned comment added by Bejmark (talk • contribs) 23:09, 13 January 2014 (UTC)
