i mean, really the market is a lot different for the model S vs the model 3.
model S is mostly bought by hardcore EV fans who, in case you didn't notice, don't have much options in the "not an economy EV car" segment
model 3 is going up against economy EV cars, many of which have much better build quality and similar features (even lane-keeping autopilot, hell that is a feature on my car and it's made by fucking GM) at the same price point.
people are going to be super angry about model 3 build quality when they get their cars for sure and musk isn't going to have a damn thing to say about it
