I've been saying for a while now that it's time we fix the tagging problems
with bicycle and motorcycle lanes by *actually including them as lanes*,
because it cleanly handles exactly this kind of situation concisely and
cleanly.  They're still lanes, just a reserved kind of lane like a carpool
lane or HOV lane.  JOSM already handles this with its lane tagging features
beautifully.  Any data consumers that can deal with lane access (which, if
they're not, this is *already* a bug, because HOV and bus lanes are things,
too) will be able to handle it without problems.

cycleway=lane
lanes=3
lanes:forward=2
lanes:backward=1
access:lanes:forward=no|yes
bicycle:lanes:forward=designated|yes
turn:lanes:forward=left|
access:lanes:backward=no
bicycle:lanes:backward=designated

Or we can just keep trying to pretend bicycle lanes aren't actually lanes
and try to figure out how to fix something while simultaneously keeping it
permanently broken because the original lanes proposal only considered
private motorists.
