Tesla somehow successfully rebranded minimalism as luxury, and that was spectacular for their bottom line while trying to sell electric vehicles to people for as cheaply as possible, which they absolutely needed to do because widespread adoption was going to be the only thing that would justify the proliferation of charging stations (where the real money is made).
Everybody else who tried to follow Tesla in the EV market (after sitting on their hands for years like idiots) thought the secret sauce was minimalism, when really it was just people compromising on features to have the ability to charge their car for a lot less money than it would have cost to fill it up with gasoline.
