I think the most important thing is to define the semantics of what is required. One problem (feature?) of OSM tagging is that there are a lot of implicit defaults, and these make it hard to use the data. I think we should be gradually defining the implicit tags (in the main tag wiki page, not in the database). By that I mean things like highway=footway implies motorcar=no. It sounds like Radfahrstreifen means that a cyclist may not ride on the road outside the lane. But with Schutzstreifen, a cyclist may ride on the road to the left of the dashed line. Or by mandatory do you mean that cars are prohibited from crossing the solid (white?) line into Radfahrstreifen but not prohibited from crossing the dashed line into a Schutzstreifen? In the US, cycle lanes on roads seem to usually have solid white lines, with dashed lines for turning places. I am unclear on whether there are restrictions on cyclists in various states (in MA, I don't believe so, beyond the standard rule that cyclists must ride as far to the right as can be done safely, which is usually less far than cars think :-). But I think cars are prohibited from driving in cycle lanes - I did see a Big Brother sign exhorting cars to stay out. In the US, my impression is that sharrows are just a reminder to everyone of the normal rules which always apply and have no real significance. In that respect, they are kind of like signs that say "Please drive nicely", or "Check twice; motorcyles are everywhere.".
