Some of you on here will no doubt be familiar with the works of the rock band Rush, whose 'Moving Pictures' album contains a song called 'Red Barchetta', basically a futurist anthem to the lure and power of a forbidden old red sports car at a time when all private cars have been banned.
There is a sense of an apocalyptic mindset starting to germinate in the minds of a lot of motorists - "petrol is going to run out, perhaps in my lifetime, it will never get any cheaper, so now is the time to go and buy that M5, that Carrera, that TVR, etc"....
.....and then go and rag the nuts off it....

I have some sympathy with this view...

Also, with scarcity and expense comes cachet and snobbery, so to a lot of people the petrol price is still insignificant, and for an increasing number of people for whom it is significant, they are still out there, buying fast, fuel-inefficient cars and saying "hey, look at me"....
