Again, you are speaking about minority, that dedicate their time to
OSM and are ready to go around on bike.

Just think, couple taxi drivers [compensated correspondingly] with
GPS-tracer turned on and SD big enough in two days will cover area
that will take bike tracer year to trace. Ok, you will not cover parks
and pedestrian-only roads, but 99% of OSM users are primarily
interested in getting around by car.

What a waste... time of the bike users can be much better spent on
markup and postprocessing of the GPS-traces.

I suspect that dedicated bike-mapper would explicitly mark road
direction as well (along with churches, rivers, bridge names, signs,
road surface and sport type that can be practiced there). What a waste
of time...

I have added to the Beginners Guide::Collecting data page notes on
priorities in data collection:

http://wiki.openstreetmap.org/index.php/Beginners_Guide_1.1

As I wrote on the page, we should run a poll on what tags OSM users
are looking for, in order of importance.
