But how is this solved in existing hydrogen cars? Hydrogen cars exist,
so surely they must have some way to at least mitigate this problem?

"How Safe Is Hydrogen?
Mirai’s hydrogen fuel tanks have been rigorously tested and proven to meet
Global Technical Regulation No. 13. * If the hydrogen sensors detect a
leak or a collision, the hydrogen tank valves will automatically close to
prevent more hydrogen from escaping while any hydrogen that is leaked will
safely return to the atmosphere."

That doesn't address the integrity of the composite fuel tanks.

That's a definite tl;dr document but as far as I got it seemed to
recommend controlled leakage before the tanks burst and tried to determine
the number of cycles before problems occur. However one paragraph was a
disclaimer saying they don't have enough real world data to be sure.
