Tesla has yet to have direct sales in TX, MI etc and can adopt some form of dealer distribution almost overnight so sales in those States can multiply.
On the topic of the now-ongoing delivery-challenge:
Regardless of what kind of presence Tesla has in the home state of a given buyer, wouldn't it make sense for Tesla to encourage the buyer to pick-up their car directly at the Fremont factory ?
I am aware of Tesla's no-bargaining policy, but they could waive or reduce the destination fee for people who agree to pick-up their vehicle themselves, reducing Tesla's logistical challenge of getting all these new cars delivered.
With the joy buyers show when getting their car, I could imagine quite a few who would inaugurate their Tesla experience with a not necessarily short drive home.
