I think it's all a joke......for the most part
Car industry; Well this is possibly an excuse to raise prices. Australia car prices are not higher than in the UK and neither are the USA car prices.
Petrol; This is just a joke, the only reason petrol prices are so high is because of the greedy government taxing it to death. The mention in this article possibly short term, well that's just silly too, we know the government will not allow prices to drop much as this takes money out of their thieving pockets.
I find the whole mess a joke with the exception of the ignorant, racist people, this is no joke and makes me sad to be English .
If only there could be a government that was run like a proper business, my goodness it could become very powerful.
