text: Yes, the zig-zag is wrong any way you look at it. I personally favor showing dedicated cycle lanes as separate cycle ways, primarily because the mobile apps I'm familiar with( OsmAnd+ & Maps.me)  do a bad job of showing lanes that are simply tags added to roadways. This is really the fault of the apps, and they shouldn't be catered to, however a cycle track that can't be readily located on a map is pretty much useless, in my opinion.
  Cycle tracks on roads should not be tagged as "segregated" since that specifically refers to shared cycle/foot paths (virtually all Calgary paths should be tagged as segregated = no to be in compliance with OSM recommendations, but almost none are - the few segregated paths that exist are drawn as two separate ways - eg Riverwalk, Parkdale along left bank of river, east end of Glenmore Reservoir)
