No, avoid the doorzone, don't cycle in it at all, I could well be dead right now if I cycled in the door zone - I had some driver fling his door open whilst a bus was coming the other direction up the road, the door just missed my handlebars.
Watch this and tell me you have any time to react when someone opens the door at the last moment.

Why endanger your life? - stay out of the doorzone and show this video to anyone who cycles because I'm sick of people cycling in the door zone and confusing drivers as to the correct place a cyclist should be cycling - I end up getting harassed for staying safe because of them.
