It's a completely loony proposal from the Department of Fanatical Twerps, the unforeseen consequence of which is that any cyclist, anywhere, at any time could deliberately cause a crash with a car for which, under the new law, the car driver would automatically be blamed. However, they do have a similar practice in Thailand where if, for example, a drunken moped driver causes a crash that results in his injury or death, the driver of the larger vehicle is held accountable and may have to pay £1,000 or so to the bereaved family. In Thailand this liability has been kept in proportion, but in the UK it could go bonkers with £1,000,000 plus being claimed from the unfortunate car/van/truck driver, bringing about yet another increase in insurance premiums and criminalising yet more of the population.
