10 days cycling around copenhagen
multiple times forced off the road usually with a nice helpful sideways drift of the vehicle in the passing lane (always fun when it's a bus)
motorists tried to helpfully point out, even from across multiple lanes of traffic, that roads are for cars and got very aggressive, even across multiple lanes of traffic, if you ignored them.
Deafened by hooters if trying to turn left from the turning lane. Apparently the "correct" procedure is cycle to the junction on the bike lane/sidewalk/pavement, stop on the sidewalk/pavement, scoot/push/cycle across on the pedestrian light, wait for the next light change if necessary, repeat scoot/push/cycle procedure until you meet up with the bike lane/sidewalk/pavement in the direction you want to go, continue riding.
if you're cycling correctly on the bike lane/sidewalk/pavement then you have to give way to almost everything (except right turning vehicles, assuming the driver actually sees you and doesn't just drive into you)
the bike lanes, especially in the morning, were littered with glass shards/trash. Also, if in doubt, toss it in the bike lane seemed to be the order of the day
very few people use bells so there's a good chance you may get other cyclists buzzing you as you prepare to manouevre (even with hand signals) around potholes/obstacles/corners; always amusing when it's on the inside of your turn.
bike theft is apparently so endemic it's pretty much ignored
anyhoo, as you can no doubt tell, copenhagen may be rated as a nice place to live but, as far as cycling and I am concerned, it was "teh major suck" (apparent shake downs on storgata, broad daylight bike theft, pusher alley in christiana, copious litter and graffiti everywhere except right outside the palace, let's go out and smash a shop window, etc.)
Strangely, I'd say that london is the cleaner city; if you could believe that. It definitely feels a whole lot less crowded than copenhagen for some reason.
