[talk-au] Special event clearways and lane=*

[Andrew Davidson]

There is a note on Chalmers St:

https://www.openstreetmap.org/note/2551595

where the question was how many lanes does this road have?

Normally I'd say:

lanes=3
lanes:conditional=2 @ (....)

the wiki suggests:

lanes=4
lanes:conditional=3 @ (....);2 @ (....)

because it wants to count the special event clearway. Now the problem is 
that I don't know what to put in as a condition for 3 @ (....) as it is 
arbitrary ie: whenever someone decides to type something into the system.

Do people have an opinion about which option to use:

lanes=3 ... and ignore the clearway
lanes=4 ... and come up with something for the condition

or

lanes=3 and use the same condition for 4 @ (....) with the idea that if 
the condition can't be parsed at least it will default to 3.
