Well at least the M1 has got another lane. Such ideas have been tried in the USA, and have not been as successful as first thought. the obvious reason for this, quite appart from the safety and Policing aspects, is that is left to individuals to make their own arrangements as to actual sharing. Unless you and say your next-door neighbour, work at the same destination, and have identicle hours, it seems a scheme doomed to failure, thought up by people who don't live in the real everyday World.
