Motorists can legally flout the rules of the road

New guidelines issued to the Metropolitan police means that motorists
can openly flout many highway code rules without risk of the police
taking any action other than a word in their ear.

In contrast, cyclists will still be persecuted for minor
infringements, such as mounting a kerb to avoid the mortal perils of
left turning lorries encroaching on ASLs.

(OK - so it's trollish wording, but that's about the position of
things in London at the moment.)
