Do you mean you see a difference between bay and lane or are both no
lanes at all.

First, I need more information which software uses this tag atm and how
it is used/spread across the globe. Not sure how far lanes:-tagging is
spead so far either. Needs a separate thread.

The wiki says to use lanes=* and at least one of lanes:backward/forward=*.

I usually add all if not 1+1=2 where only lanes=2 is needed but as
demonstration I tried to be exact as possible and rather include
unnecessary tags.

Would work in this case.

Not the same, see below.

But not fit real world as we loose the different access tags per mode.
Above example has a bus lane (blue sign) where taxi and bicycle is
allowed (additional white sign "frei").
