• Horse(back) isn't really a type of vehicle. Can we re-draw this? --achadwick 13:18, 10 March 2009 (UTC)

  In some countries it's under unmotorized vehicle, in others it's a category of its own. Just as a Segway is a pedestrian in parts of the world and in others must be registered as a moped (or equivalent) - which would require licence plates, driving lights etc... But I recall that this picture was meant to be for illustration only and the exact definitions would be written as a text/list/table. Alv 14:27, 10 March 2009 (UTC)

  • Somebody should really do that table... :) --achadwick 18:32, 11 March 2009 (UTC)
  • For the same reason that mopeds are in some countries treated as bicycles by the law, and in other countries as small motorcycles, I guess we have to keep to a more factual, internationalised definition. Using the English word, admittedly :/ I'm in favour of spelling it out fully, forcing myself to write motorcycle=no,moped=no should powered two-wheelers be specifically prohibited along a stretch of road. --achadwick 18:32, 11 March 2009 (UTC)
