Looking out for people so as not to crush them to death is not some kind of special extra service - it's the bare minimum that should be expected from a person operating anything that dangerous in a public space. And that includes looking out for people who make foolish manouevres (although of course in most cases where people are killed and injured by drivers the victim is not doing anything untoward or unusual). Pedestrians and cyclists slipping through small spaces amongst things, whether well or badly judged, is what happens in all urban areas where there are lots of people going about their business. It may be nervewracking for drivers, but tough - it is those who are operating the vehicles that bring the extraordinary danger to the situation that need to adapt - if they can't, then they are not fit to share public space.
