I am really not sure how hydrogen race cars will react to crashing, I hope they already have that squared away, but the thing is you really never know until one crashes. Having said that, I still thinks the HFC is really the way to go for road vehicles with the already easily adaptable infrastructures and the especially to the way how the vehicles can be refueled.
As much as how “High Tech” our cars are today, we are still essentially using the barbaric 150+ years old “controlled explosion” engine format. :rofl
