Tesla can't sell more cars than it can make and it can't make them fast enough. Trust me, Elon would be way into brand marketing if that is what was required for the mission. The fact is that the master plan is fundamentally a Marketing plan. Build a super sexy, super fast car.. why? To elicit lust for the brand. Then build an even sexier and not powerful sedan? Pure branding. Elon may not want to admit but he is marketer. Look at SpaceX. Every rocket launch is broadcast, every rocket is white and freshly painted after being burned on reentry. It's all brand marketing whether Elon wants to admit it or not.
The Tesla stretch is 100% because of this brand marketing. They could have made a very cheap, small compact EV that was mission focused but the mission would have failed. The key component of the mission is not selling everyone an EV, it's forcing every competors to make compelling EVs. The mission fails without that cause and effect. It's as clear as day to anyone with two eyes. Tesla's top down assault on margins only happens with super sexy, fast and lust worthy cars. That's brand marketing 101 right there.
Don't confuse marketing and advertising. Strong brands don't have to advertise as much. It's more strategic around specific product launches then the brand as a whole. Tesla's are it's advertising and they more demand than supply. A temporary squeeze if demand into 2 QTRs will but change that and the demand rubber band will snap back with a vengeance in the US as all those new Tesla's dominate the roads.
