A Tesla dealership in Miami.

With some states either banning or considering a ban on vehicles being sold directly by an automaker, Tesla Motors is petitioning the White House for help in swaying opinion. The electric car company has launched an online petition it plans to send to the White House by the end of next week.

The goal: Acquire 100,000 signatures from those who think states should allow automakers to sell vehicles directly to buyers and not be forced to go through a third-party dealer.
