Do the 'powers that be' REALLY know which mode of transport is most 'green'?

Is it REALLY 'green' for there to be buses riding round with only one passenger?

Is it REALLY 'green' for the government to charge extra duty on planes? Where does the money go to... only the amazingly naive think it will go into research on creating more fuel efficient planes!

And do the government have any idea which actual vehicles on the road are least 'green'? They pretend to know... and charge vehicle excise duty according to their own prejudices!

Have they any idea how fuel inefficient small old cars driven by 'boy racers' at at least twice the legal speed limit in built up areas are? ... using the council's own free, and absolutely brilliantly designed slalom courses [sorry, traffic calming schemes!]... yet they are classed as 'green'!

Trains... why do we see shrinking train sizes? Does it have ANYTHING remotely to do with the extortionate ticket prices? Ask for a ticket and what comes into YOUR mind... I know what I think. I always want to ask if that includes a share in the railway company!

More suggestions will be gratefully received!
