Getting doored is honestly terrifying (I don't say that lightly). I bike and longboard frequently, and I'll avoid bike lanes if they are alongside parked cars. And this is in Boulder, one of the most bike friendly cities in the US: http://www.bicycling.com/culture/advocacy/2014-top-50-bike-f...
Cyclists need at least a metre of space on the nearside at all times. It's your escape route if cars pass too closely. It's your protective buffer against being doored or against pedestrians stepping out into your path. Hugging the kerb gives you nowhere to go in an emergency.
Be brave and take the lane. If you delay other road users, let them honk and shout - that metre of space is literally a matter of life and death.
