That depends on where you are. In Germany it is perfectly legal for a cyclist to pass waiting cars at a stoplight on the right if there is enough space, because it is safer for them to wait a the front of the line than somewhere hidden between cars. Especially if they can get to a marked waiting area like this: http://commons.wikimedia.org/wiki/File:Radaufstellstreifen_%...
Seems like cyclists dangerously undertaking (passing on the incorrect side) causes these problems. Much to the annoyance of cyclists, smart motorists would position the vehicle to prevent undertaking maneuvers when approaching a turn. For cyclists intending to go straight, the cyclists needs to take the lane, positioning themselves so they can't be overtaken by vehicles intending to make a turn.
In all cases, motorists needs to be aware of the more vulnerable road users and cyclists should take more precautions when sharing the road with 2+ ton vehicles.
From a cycling commuter for the past 5 years, 37km one way, in the Tokyo Japan area.
Some US cities have that, too, but not all of them. In the ones that don't mark spaces like that, though, there isn't really space for cyclists at the front and even pedestrians aren't particularly safe from motorists looking* to make a right turn at a red light.
* On further thought, maybe that choice of word is inappropriate.
