I fall squarely in the camp that says they are just not suitable vehicles to share the road with other occupants. Frankly they make motorbikes look safe. Of course no government is willing to give up the money or the space to dedicated infrastructure.
So as you say, once a month or more a cyclist dies when a lorry turns left. I've watched a cyclist literally crawl from underneath a bus that knocked her off - and it's a contributory factor to my never cycling in London.
