> The key difference between Toyota's approach and Tesla's was simple: Tesla built out their own charging infrastructure.

No it isn't. The key difference is that Telsa picked the right technology and Toyota didn't.

Tesla could build its own infrastructure because the grid exists already and building chargers is not that hard.

Toyota couldn't because building hydrogen infrastructure is insanely incredibly stupidly expensive. Even had they tried, it would have been a gigantic money shredder.

Building fuel-cell cars is really expensive, in addition the the infrastructure they are also losing money on each car.

So basically, your asking Toyota to spend billions to build infrastructure that loses money, and more billions to build cars that lose money.

The right technology choice matters!
