Let's be clear.

The reason Toyota isn't all-in on EVs is because Toyota is the dominant player in a rival technology: gas-electric hybrids.

This is extremely clear business strategy: Toyota doesn't want to cannibalize its marketshare in hybrids.

Toyota pushed hydrogen fuel cells for years to obstruct EV adoption, just as Elon Musk pushed hyperloop to obstruct high-speed rail adoption. Both hydrogen and hyperloop are fantasy technology: decades away or completely impractical (hyperloop.)

Only after EVs were widely adopted in many countries did Toyota start moving towards EVs. That was a logical business strategy for them.

Toyota isn't all in on EVs because they make lots of money from hybrids. The end.
