The article mentions "motoring poverty" as if it is something that needs cured by reducing the cost of motoring vs. reducing the need for motoring by providing more, better and less-expensive alternatives.
I kind of think that the article is actually downplaying the true cost of motoring (they've got no real vested interest to make it seem as expensive as it really is) For instance, googling suggests the UK average car insurance premium is £971. Which would put the calculation for weekly insurance costs in the "study" (£420) under half of the actual average. £250 per year on maintenance seems hugely generous, last time I had to stump up for some repairs to a front-wheel drive CV joint it was more than that alone. And they've budgeted for 2.4 gallons of fuel a week, which would unlikely even cover my 12 miles a day commuting by bike.
“To make any meaningful difference to those on the lowest incomes the rate will need to be cut much further.”
That's some perversly backwards logic, which doesn't surprise me at all! And it hardly surprises me that the rent-a-quote shadow minister for cars is of exactly the same mind and almost fell over herself to get the phrase "ease the pressure on families" in her statement. I wonder would any minster be standing up saying that we need to cut the duty on tobacco because "hard working families are drowning under the price of cigarettes"? No, they wouldn't, but until we get a governmental and social acceptance that for many people motoring (or the amount of motoring they do) is an optional not a necessity, we won't get much change. It's recognised that we tax tobacco how we do to discourage its use and to meet the costs of its negative side effects on the population. However, fuel duty is just the government screwing "hard working families".
