>> The reason to use separate ways for trams can be seen in the other tram
>> tracks I mapped:
>> You can clearly see that very often the rails don't follow the asphalt
>> where the cars drive. Cars can make 90 degree turns, the tram rails need to
>> follow smoother curves.
>> So it's only in situations where buses follow the tram bedding:
>> that one can have common ways for the tram and that service road.
>> * For normal streets we draw 2 ways for the tracks and 1 for the asphalt
>> * For dual carriageways we draw 2 ways for the tracks and 2 for each side
>> + sometimes a service way between the tracks, when the buses use it too.
>> It's rather exceptional that the service road and the tram rails can use
>> the same OSM way.
>> Keep in mind it's only a model to represent reality. A model which uses
>> lines for what in reality are areas, so whatever we do, it will never be a
>> perfect fit.
>> I'm sure André won't agree with me, but to implement the solution he
>> proposes, we'd have to restart OSM from scratch. And even though it may
>> simplify and solve some things, it would make other stuff a lot harder.

>>> show trams, but if we start tagging them, it will probably start rendering
>>> them. Right now, I use psv:lanes:forward=designated|no, because psv means
>>> all public service vehicles.
>>> And in my town those lanes are reserved for trams, buses and taxis.
