I think there&#x27;s a general conversation that people seem to be ignoring. We currently use general taxation as a way to discount certain behaviours. Tobacco&#x2F;Alcohol duty more than pay for the costs that these forms of consumption place on society. We are even prepared to consider a sugar tax.<p>Yet the moment we ask the question, why cars do not pay for their costs, nothing happens. Fuel duty should cover road maintenance and the health costs (Killed or Seriously injured, obesity, and pollution related illnesses).
