Why cars may be greener than buses!

BBC's "Ethical Man" makes an interesting case as to why cars may be more efficient than buses and trains. It's very interesting, so I wanted to share it. Don't be so eager to start driving though! Towards the conclusion he writes:

"Even though travelling by car can be less polluting than public transport you should always take the public transport option.

That's because buses and trains are running anyway. They will be out there generating CO2 whether you ride them or not. So when you choose to take your car, the pollution you create will be on top of whatever the public transport option is producing."
