Hypothetical law change? Lorry on bike: lorry's fault. Bike on ped: bike's fault

I'm not so sure. The first two collisions involved the driver swerving out of their lanes. How many drivers will think 'I can change CDs without leaving my lane, so it's all-right for me to do it.' ? Even the last collision was easily avoidable - cars in front are not hard to spot. How many drivers will think 'the advert is clearly exaggerating, i'm not that dangerous so i don't need to change.'?

You're right about the exaggeration in swerving but I think they way that it's shot in a "Police, Camera, Action" style makes it seem a lot more real than the usual ads of this type.
