George Monbiot: I’m all for putting more vehicles on our roads. As long as they’re coaches in today’s Guardian.

The M25 has 790 miles of lanes. If these are used by cars carrying the average load of 1.6 occupants, at 60mph the road’s total capacity is just – wait for it – 19,000 people. Coaches travelling at the same speed, each carrying 30 passengers, raise the M25′s capacity to 260,000. Every coach swallows up a mile of car traffic. They also reduce carbon emissions per passenger mile by an average of 88%.

Finally, someone has noticed Emperor Eddington’s new threads.  As ever, Monbiot addresses the real issue without the encumbrance of the straitjacket of party politics.
