This is an interesting one. The BBC defence will be that the cause and effect are related. A cyclist died - newsworthy, a traffic jam occured - newsworthy. The problem will be to prove that in similar accidents, the inconvenience to motorists was not given such prominence in the original article. I can almost hear the silky smooth defence which will claim that 'cyclists are making too much of this - well cyclists do this don't they' in a patronising manner. Conveniently, reading today's BBC Scotland pages, there is a report of 3 motorists dying, but no mention of delay.
