I use the cycle share scheme (known as Boris Bikes after Mayor Boris Johnson) whenever I can in London.

One consequence of using the bikes however is that you spend a lot of time behind buses. When you get stuck behind the old diesel buses spewing-out dirty fumes it’s horrible and you really appreciate the new generation of ‘green’ electric buses.

Brilliant Idea #235 is that these green buses create a moving pathway through the traffic by programming the traffic lights to go green for green vehicles.
