And just how did he decide to execute his grand electrified vision? By backporting electric propulsion onto an existing SUV platform. Yeah, this is exactly the moment where this particular piece of journalistic spin comes crashing down.
The RAV4 EV was sold only in California precisely because it was a compliance car. Toyota simply decided it was cheaper to leverage their existing investment into Tesla to produce an EV on the cheap that could get them the required environmental credits so they could continue to sell their actual vehicles without having to buy the credits at a (at the time) large cost from other manufacturers. It was a simple localized business decision, not some grand strategy.
Of course Musk doesn't just ridicule fuel cells, he affectionately calls them "fool cells". As someone who builds his businesses by reasoning from first principles, he justifiably doesn't understand the idea of swapping a 20% efficient (if you're very lucky) combustion engine with a 10% efficient, experimental fuel cell when you could instead use a dead simple, clean and 80%+ efficient electric motor.
