And they evidently are working on it. But to say "release it now, don't make me wait 5 years" is beyond ignorant.
Anyways that's what I read into it.
As consumers we assume hugely successful historical automotive powerhouses like BMW would have something ready to go NOW because they've been working on it already for 5 years (or ten years+ considering Prius).
Maybe not always fair, but it's generally what people are going to assume.
Maybe if the OEMs had spent the last 10 years designing and building electric cars instead of putting out diesel agents that broke the law in dozens of countries they would be in a better position.
