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

The OP stated "In a bike on ped accident there would be a presumption of fault on the part of the bike"

Which no one here has agreed with, which sounds as if they have regular accidents with peds, which is indeed a worry.

If a cyclist collides with a ped they both could be badly injured or worse (which is not true in a car).
