Yeah, not so much. Given that London Bridge has a cycle lane, a
separate bus lane (also for cyclists) and a normal lane (for
everything else, and buses, and cyclists) on one side of a
dual-carriageway then your simplistic generic system won't work. Also,
I challenge you to come up with the user interface that doesn't
confuse the contributor when you say "which side of the road is the
cycle lane on" and they say "the left" but they need to mark it as
cycleway:right because they are facing the "wrong" way on a two-way
street.

The main objection to "left" and "right" is that most roads don't have
an intrinsic direction, certainly not one visible on the ground. At
least oneway roads have a fairly obvious direction when you're out
mapping.

Cheers,
