Quite a few bike lanes on my commute but they are mainly narrow ones so I'll be right on the edge of them anyway - which does cause problems when militant motorists drive 2" from the white line. Couple of sections run right alongside parking bays so prime dooring territory, I avoid those which winds up motorists unfortunately, sorry but my safety is my priority.
Couple of mandatory ones in good places where they would really help cyclists but lots of motorists ignore them and drive over them cutting you up or running you into the pavement etc.
Also a couple of dodgy mandatory ones which if you follow could well leave you in pretty serious conflict with other road users, I avoid these and wince when I see others using them.
I regularly ride on a DC the cycle friendly alternative has 3 subways 15 slalom gates and takes about 10 minutes longer and a lot more energy. When I don't feel upto the DC I use a shortcut of my own design including a short dirt road section and ignoring atleast 1 nocycling sign
<Edit>Proper offroad bike lanes seem to be a bit like motorways, supposedly taking you in relative comfort from A to B via slightly longer but easier to negotiate route and generally quicker. Unfortunatley bike lanes tend to get covered in glass, debris, slalom gates, dog eggs, random walkers etc. Hardly anyone would use motorways if they had similar inconveniences and worked out a lot slower would they?
