Maybe that was true for pre-2007 Toyota management.Those folks at Toyota are NOT dummies.
I would need to see evidence that show current Toyota management are NOT dummies.
Yup. On purpose like deer in headlight freezes as car plow into it.They are stalling with a purpose.
There will be no surprise. The issue is not that solid-state does not exist.It wouldn't surprise me one bit, if they stall and stall. Then, like a magician pulling a rabbit out of their hat. Toyota says, Oh look we have solid state batteries!!!
The solid-state problems are
1. need lower price (cheaper than LFP)
2. large scale production (multiple tera watt hours per year)
The factory that can do both will not exist before 2030s so will NOT be in Toyota's 2023, 2024, 2025 or even 2030 hat.
