To be fair, there are lots of manufacturers
claiming that their petrol engined cars will do 50mpg (or more). There are very few cars actually doing 50mpg in everyday use though, especially in cities where the main problems are.

But, much like the emissions scandal, the manufacturers seem to be getting away with advertising figures that are unachievable in the real world.
It seems odd that politicians of every hue have spent the last 20 years doing everything they can to encourage people to buy diesel, but now it's the fuel of Satan and must be taxed!
Surely if it was that dangerous they'd be taking all these killer cars off the roads?
Or is it simply another way of raising taxes?
