It's also a meaningless metric because most manufacturers sell multiple models of the same type. Toyota has Corolla, Prius, Camry, Crown, Mirai, Ativ, Century, Belta - all small-mid sized sedans. Add them up and they outsell every Tesla model put together.

BYD has 61 different models in its lineup compared to Tesla's 2.

Yes for example in 1955 it wasn't, the OP was suggesting Tesla is doing badly now.
