Lots of dealers and maybe some US automakers could go under due to thinking they could survive by selling gas hogs to the marketplace.
Why? They thrived! Or, do you mean that they could go under if they don't modify their strategy from here on in?
Instead, they should have been real leaders and told people they should buy true gas sippers. Should have built them too. Silly Detroit boys.
Telling the consumer what to buy is a terrible idea from any point of view other than that of a busybody or a company with a monopoly. Building true gas sippers is fine, but building too many would have been a death sentence for any manufacturer who did; they never would have survived until now when it's much more feasible. They built what the market would buy.
Except in a monopolistic market, the buyers are in control.
