Agreed, we map roads and attributes of those roads. Sorry, I thought you
were suggesting a tag with the meaning "cars have their steering wheels
on the left|right".

It is not illegal to drive a car with the wheel on the "wrong" side - millions of Europeans do it regularly, both on holiday and because certain models of car are only made for certain markets. Let's stick to driving_side referring to the side of the road. By the way, when Samoa changed from driving on the right to driving on the left a couple of years ago, that was because most of the vehicles were imported second-hand from Australia and therefore had the steering wheel on the right anyway...

You could simply tag the country with "driving_side=right/left" and use the same (but with the opposite value) on those streets. That said, I think driving side also implies "driver side" inside the vehicle. Though I find it very unlikely to!
  see this
information in use one day, it's best to define this meaning early on. A change of driver side requires either a change of vehicle or some special vehicle that can drive on both sides. In the case of your city, driving side changes, but driver side doesn't. You could include that in the description of "opposite". One more thing: this only makes sense if there is no physical barrier between the opposite traffic directions. If there is, then it's just a separate way with no special change in driving side.

So far so good, but according to taginfo it is used only once on a relation, however there are some uses on so!
 me ways,
and even nodes(?). There are, in my city, a couple of streets that have an inverted driving side. So I am going to extend this tag's documentation to include ways that have it's driving side opposite to it's country's normal driving side. Is there any interest of using it on countries? If there is not, I will exclude the possibility of use on countries from this tag's documentation. Perhaps, with this new definition, this tag could be redefined to have only one value: driving_side=opposite (this way, it could avoid any confusion about it's use) What do you think? _______________________________________________ Tagging mailing list Tagging at openstreetmap.org https://lists.openstreetmap.org/listinfo/tagging [1] -- Fernando Trebien +55 (51) 9962-5409 "The speed of computer chips doubles every 18 months."
