there is really no reason for tesla(or any car manufacturer) to sell to dealerships if they care about the consumer. in most cases, the manufacturers make x copies and sell them all to the dealerships. they dont really care if the end user likes them or even buys them because theyve already made their money.
in the best case scenario, everyone buys every car... but it costs the end user 10-20% more than the cars cost the dealerships. if tesla cuts out the middle man, they can charge the normal dealership price, but for everyone and still make the same profit.(this also makes their cars cheaper than the competition).
dealerships are outdated and are in need of destruction.
