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".

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.

According to it's description, this tag should only be used on countries, and it describes the side of the traffic in the whole country. 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@openstreetmap.org https://lists.openstreetmap.org/listinfo/tagging [1] -- Fernando Trebien +55 (51) 9962-5409 "The speed of computer chips doubles every 18 months."
