What's unique for Toyota is that their hybrids are sold like a pancake. Hybrids also uses batteries but it uses far less. Battery supply is the current constraint for xEV. Since they can sell many hybrids for less battery use, I understand that they don't want to "waste" batteries for BEV, but it makes bad reputation for slow BEV transition.

It's the classic innovator's dilemma, but hybrids are also great vehicle for who can't afford BEV for some reason now. Still, I think they should released moderate BEV (like Nissan Aria?) in 2021, even if they ship very limited count.
