Posters here have claimed earlier that Tesla doesn't go to auto shows, as it spends $0 on marketing & advertising, and has a long backlog. To quote Elon, "the car sells itself". Attending two shows within 1-2 months should mean something then.
Tesla goes to auto shows, I don't recall anyone claiming it doesn't. The Model S was at several. It would be weird if they weren't showing off their newly-launched product. Saying the car is selling itself, at a point in the past when they were trying to suppress demand, does not mean they would never promote their product once it launched. If they weren't going to auto shows, bears would be using that as FUD.
