My hope is that high fuel prices will begin to focus drivers minds on to reducing unnessary car use to the point that other options start to become more viable – making fewer journeys ( do you really need to drive 1mile to nip to the shop for a loaf?) using public transport more ( provision of which would improve with more users/demand and greater revenue streams, build it and they will come….), working from home where possible, living closer to work/schools, etc. Likelihood is it wont make siginifcant impact on reducing car use – society has been engrained to the point were cars are absolutely essential for human life – and we are wholly dependent on them at any cost, much to the delight of the oil companies, tax collectors and the car industry, but hugely to the detriment of the natural and built environment ( light, noise and air pollution, cancers / CVD from inhaling exhaust fumes, greenhouse gas emissions and the impacts on climate, obesity from lack of physical mobility, accidents causing injury and deaths and loss of green spaces to parking lots and road infrastructure).
