Here is a concrete mixer truck at Oxford Circus at midday. It’s got blind spots the size of small cars and eight wheels to maim people with. It’s stopped past the line so the driver can’t see the lights, and will slow down and destabilize cyclists behind it once the light changes. It’s blocking the pedestrian crossing, contributing to the already chaotic and crowded pedestrian space.
It’s got multiple “cyclists stay back” stickers. Safety first.
