You know what else will be braindead in your nice world? The child who runs out in front of a car after a rigid tight-angled metal corner drives into their skull. These regulations aren't about blame or "drivers/pedestrians/cyclists should be more aware!", they're about reducing or avoiding as much harm as possible when things don't go to plan and an accident happens.
You seem to be desperate to talk about blame but ultimately they're called accidents for a reason. Not because we want them to happen, not because we can always prevent them. Regulations like this are about changing the outcome, not the initial reason it happened.
