Their self driving is not the best in the world, they're not really rated all that well in self driving, they just market it that way.

Their infotainment system isn't great, their dashboard for the model 3 is in the middle of the car, and there's no speedometer where every other manufacturer puts it. The infotainment system also controls the wipers, climate, and everything else with a touch screen, making it less useful and more dangerous for an average driver.

Their manufacturing isn't outstanding, they had a target goal of full automatic factories, but instead have to rely on underpaid, nonunion workers, and it shows in the build quality.

They don't supply parts, info, and equipment to 3rd party manufacturers, making it more expensive to maintain and fix their cars.

Their batteries are average, but they intentionally lie on the range estimate to make them look better.

Basically, aside from the advantage of being the first major EV manufacturer, everything else commonly associated with Tesla is just marketing lies.
