Toyota invested heavily into the R&D which is distinct from tooling up to produce 70kwh battery packs by the millions. They've sold maybe 20k hydrogen cars, globally over the course of a decade as a pilot. They also sold 4k RAV4 EVs, are working on EVs with BYD and CATL, which means that they're keeping their finger on the pulse of the industry while also staying out of the lithium/neodymium pissing contest which they simply cannot win. The reason Chinese EVs are such a good deal is because all of the hard-to-source stuff is under the same roof because China doesn't really have a fossil fuel story. Their hope with EVs is that the current approach to making them is simply not sustainable on a global scale and that the emergence of less resource-intensive technologies will saddle all earlier entrants (that aren't subsidized by nations) with debt.
