Basically if you read between the lines it says:
Dear Voter,
Thank you for taking time to sign the petition against road charging. Your objection has been noted and will of course be completely ignored. We shall now spend a few months bleating on about the environment and try to put a spin on it in an attempt to get the green brigade and the mindless numpties on board.
Fear not as despite living in a democracy we will do as we like regardless of what the public feels and will make a fortune whilst doing it.
Your smarmily
Tone
Well that's my thoughts on the response anyway
