So, are we to take it to the car you bought was a model 3? And, did you know that two product announcements have already happened?
Years of thinking beats hours of thinking anytime. Especially group think. I don't know how long you thought about it, I'm just saying that people who have deeply thought about it have ideas that are different from yours, don't discount them just because they're different than you. They've had some time to think about this.
No, I bought a 2016 model S. As I said, test-driven from the service center showroom where I placed my order. If "years of thinking" leads to OP saying "Omg people are going to have to mail paperwork back and forth to sign and won't be able to pick up their cars" then I'm absolutely going to discount it. Not because it's different, because that's straight up wrong, ignorant, and spreading misinformation/fear that is poisonous to this community.
