Should electric car companies set up their own dealership network?

The ongoing battle between Tesla Motors and the Texan lawmakers regarding the direct selling of Tesla cars to the general public has certainly opened up a can of worms. Should electric car companies consider setting up their own dealership network?

Oh yes the electric vehicles should set up there own dealership network so that they can establish proper market

This would also bring down the cost of EVs which in itself should make them more popular. Is it a valid argument from the government to say that it is concerned about after service if EV companies sell direct to customers?
