Its interesting and perhaps correct that women may cycle less assertively as you suggest. I'd say however that these lorry drivers don't see what's on their inside. I'm not a cyclist but I'd say if I was I would NEVER drive up the inside of a lorry or bus, whether they were indicating or not, I simply would not trust them. It seems that most of the deaths are where lorries turn left across a cyclist's path. It may be that men, in general, cycle with more speed hence being able to get away from traffic more often, but there are plenty of male cyclists dying too, so no cyclist is safe, really its very dangerous in rush hour, too dangerous for me. I would add that as a driver, cyclists should be aware that drivers have a lot to concentrate on in front of them as well as in the rear view mirror and cyclists should never assume that even a car driver has seen them come up either side of their car.
