Most people want none of this to happen. Mainly those who do want it, are those who don't know enough about cars to understand the factors those with an agenda are trying to sweep under the rug.

Further, CO2 emissions are an insane thing to avoid, by simply planting more trees we can counter that. The key is not ruining automobiles, it's driving less.

The government buying new cars and selling old cars to the public does not take them off the road! People buy cars, public included, to drive them. This would result in taxpayers subsidizing poor people having cheaper cars so they can drive more, in addition to the non-green manufacture of new cars, increasing the problem on every level.

Consumers are not concerned with CO2. The only reason it seems as though "some" of them are is because those who are, are vocal about it while those who are not concerned have no reason to be vocal about it. Yet.

What these new more expensive cars proposed for 2016 will cause is more people to keep their old cars, instead of reaping the smaller perpetual improvement in economy and emissions that has taken place in the industry year after year without such a mandate.

As the title already conceded, Consumers are hesitant, don't want this. If there is a difference that's important it's getting rid of 2 cycle engines found in every other affluent home and used several times a week for lawn and landscaping purposes. Doing that instead tends to increase the reliability of the equipment as well as lifespan and emissions, reducing manufacturing and disposal issues. Some aren't even aware the typical 2 cycle engine is rated for a mere 50 hours!
