Hydrogen vs. Battery Electric Cars

Is this an infrastructure promotion?  Hydrogen systems will need to keep all the drilling and pipelines and refineries and gas stations - This car may be electric -- but its infrastructure is carbon fueled.   More bothersome is the tone of your message -- it seems like a hard sell, rather than your genuine curiosity and exploring science.  I guess you are changing your style - you're promoting a technology .   Also the timing of this seems suspiciously close to the release of the IPCC report - a document that is far more important - and carries far more physical science than your shilling for Toyota. Humans have to choose between survival or using carbon. Any more carbon shortens our future.  We don't have time for dream transition and pseudo green.
