The fact that they already sell the most popular electric vehicle in the US and Japan, and have done so since they launched the very beginning of electric vehicles, over 25 years ago? (Pruis)
That is a matter of opinion. As a brand new technology, I think a market share approaching 10% is incredible. Only fans thought this was possible even 5 years ago.
Didn't the Model Y outsell the RAV4 in 2023? I guess there are estimates that go both ways on that, but nobody really disputes that the RAV4 and Model Y are neck-and-neck. Would be nice if Tesla released actual numbers.
