GM can't "kill" the electric car. Any fool who wants to attempt that
business is free to try. There are already several vendors, though
most are little more than garage customizations or fancy golf carts..

Remember back to the early 1970s when the U.S. Department of Justice
was proposing to break up GM into its constituent parts because it was
"Monopolizing the auto industry." So if GM is a monopoly, then if GM
had continued to sell its electric car at a loss, it might have been
construed as a violation of antitrust legislation, selling at a loss
to force out smaller electric car companies. GM would be tarred as
abusing its "monopoly" power, selling at a loss to run other electric
car companies out of business.

GM can't win. They're condemned when they screw up, and they're
condemned when they succeed.
