GP is correct and more relevant than you think, because fuel efficiency is immediately linked with the hope of avoiding global warming. Unfortunately people believe too much that "we can maintain our lifestyle without breaking the emission limits that we set", and the truth has to be reminded: We can't.
We need to reduce our lifestyle. Live closer to workplaces so we don't need the car at all, which requires a complete rearchitecture of the cities where jobs are knit with housing and public transport, like Sydney or many places in Europe. US people have a difficulty understanding this, because petrol have been so cheap and untaxed for so long that they've built their cities around "1 car, 1 person" - and now they secretely hope for fuel efficiency improvements "to maintain their lifestyle". No, sorry, they're just killing the planet.
"What about China, who pollutes much more?" Yes, they should be allowed to reach their economic development, because US should pollute much less per inhabitant. An American emits 6x what it should, a Chinese person 1/6th.
This is why GP wrote this warning. And it's important because some people still don't believe it.
Similarly, cigarette packets still have to remind "Smoking kills", because a lot of smokers aren't persuaded yet.
