Not this one I'm afraid... ill informed and innacurate.
1. Taxation does not target 4x4's... it targets higher polluting vehicles.
2. We have a right to choose to drive any car... the government have a right ifnot a duty to influence our decision through taxation, limiting opportunities for use or any other tactic they deem relevent.
I accept that some larger vehicles are more polluting, I accept it costs me more to drive, I accept that opportunities for off road use are reduced/reducing.
Until the make/model I enjoy is made illegal or I can no longer afford to drive it at all, I'll continue to use it daily or occasionally as government policies/personal financial situation dictate.
