Very interesting post, gcl8a. Confirms that I probably wouldn't want to ride a bike on those Denmark streets. Give me Toronto any day over it, with all its gridlock and bad drivers and, and, and etc...
After all, if I find traffic really bad, there is always a sidewalk, which seems to be about as safe and efficient as the bike lanes you are describing.
I do believe in well-engineered bike lanes in some places, as long as drivers are as abysmal as they are anyway, but not this sort of attempt at total segregation of bikes from traffic flow that is simply confusing and frustrating.
