Tesla's cars utterly dominate the sales charts for every segment they are in. If they're only being bought as a niche car, then I guess every other luxury automaker's cars are even more niche.

As an owner of a Model 3, I will say that it isn't just a really great car, it's the best car I've ever owned or driven. There are SO MANY different elements of the car-owning experience Tesla redesigned to make dramatically better for the user, not to mention the incredible performance of the car.
