In stead of creating traffic jams and helping make more Co2 lets get to our destination as smooth and quicker as possible. I do not drive to London every day because I want too I do it because I have too.
Scrap Bus Lanes and get the country moving again. I sit in the London traffic watching Bus after Bus using the Bus Lane with just a few passengers on board, a good example is Gower street and New Kent Road. Open up the roads and get rid of the 'Traffic Calming' barriers which turn the side streets into 'Dead ends'
