"If democracy was working properly, and the legislatures was implementing the will of the people, something else would be happening…and there would not be legislation trying to artificially restrict direct sales."

Tesla represents a threat to the current market. Not only has it benefited from government subsides (this is very hypocritical considering the bailout), it has shown that a reliance on oil for cars is not necessarily required. Alternatives, that are realistic, are out there and will only be developed further.
Those with an invested interest in dealership and oil production see that if Tesla becomes affordable to the middle class worker, people will stop purchasing products the investors own. They will lose money. Thus they must lobby government to prevent competition to insure their own future revenues.
People who are wealthy enough have been buying cars directly from the manufacturer for years. I know BMW offers a full customizable interior and extras for those that preorder their car a year in advance directly from the factory.
Tesla is not offering anything new. It is just that their car is the beginning of entire change to the current market. This scares people with a financial investment in the status quo.
