Mandating more electric cars on the road than the infrastructure would allow would be... dumb? Not even an option? Economically catastrophic?
Automakers in the UK are flipping out because they recently pushed back their overly ambitious date for eliminating ICE cars, which the automakers were supposedly (I'm skeptical) already tooling up for. You can see how being early comes with its own risks and costs for a traditional automaker making the transition.
None of that justifies Toyota's effort spent farting around with hydrogen, of course.
