OK HHOgas, I understand that you are fearful about lithium-ion batteries catching fire...
However, you are perfectly comfortable - in the case of the BMW SUV highlighted in you article above - to be sitting not on one, but two hydrogen tanks sitting at a pressure of 700bar (or ~690 atm, or 70,000 kPa)?
Just to provide some context, a typical industrial gas hydrogen cylinder is pressurised to a mere 13,700 kPa (see https://www.boc.com.au/shop/en/au/hydrogen--industrial-grade--compressed).
That means the entire 700bar hydrogen industry standard for hydrogen cars is operating at about 5 times the pressure of conventional industrial hydrogen gas cylinders.
So, assuming it is indeed the future of transportation, you would feel completely comfortable with every car carrying one or possibly two of these highly pressurised cylinders at high speed through traffic.
If you listen to the car manufacturers promoting hydrogen technology, they say "trust us, it's safe".
... incidentally, they are the same car manufacturers who for decades have been telling us about ICE cars "trust us they are clean".
