Whats to stop a NJ resident from going to NY to purchase a Tesla direct? Is their a a big financial penalty for doing so when registering? What is to stop a grey market of NY residents reselling them to NJ consumers if so? This makes no sense.
It's just to annoy people who don't know what they want. They can still do test drives in NJ, but can't talk about pricing, options, financing options etc.
And when Tesla creates a Oculus Rift based VR showroom? What if there was a fancy VR showroom in the mall where several different vendors could show there wares - would Tesla be the only company banned? It'd be fun watching that battle.
You would take delivery at that address, and then re-register the vehicle in your home state after the title was in your name.
