This isn't true though, is it? I'd much rather live in a world where we all drive petrol cars but you are exaggerating somewhat here. Whether it's by enough of a margin to make financial sense, a diesel engine is more fuel efficient than the equivalent petrol engine. This is why people were incentivised by government to buy them in the first place - they use less fuel and they emit less CO2, so an environment has been created whereby fuel is expensive and CO2 drives (until this year) taxation.
The result is people buy diesels - they want to use less of an expensive commodity, fuel. Look at a market where fuel is not punitively taxed, like say the US or UAE, and you'll find almost no diesels.
It used to be the case that diesel was a complex nightmare and petrol was simple and reliable, but those days are long gone because now the average petrol engine is just as full of complicated direct injection turbocharger systems and even particulate filters are on the way.
European governments have created an entire market for these things and they cannot now turn around, say LOLLLLLL and screw everyone over who participates in a market they crafted over decades.
I drive a diesel simply because it's the only realistic choice in the market segment in which I buy my cars. The petrol versions are noticeably less efficient so nobody buys them and you can't find them used. Would I rather pick a petrol model and pay 30p a litre less for fuel? You bet. Let me know when this utopia exists.
This whole backlash is about 15 years too late. Talk about closing the door after the horse has bolted - by the time anything meaningful shifts in terms of vehicles on the road most diesels left on the road will be Euro 6 anyway and the really bad ones will have been scrapped naturally!
