I drove 1800 miles in a Hydrogen Car

What would you do if you neglect to watch your fuel and end up running out without any fuel cell stations nearby?
Also it makes sense that the actual hydrogen storage is super secure. What about the lines from the tank to the fuel cell? What would happen if the lines sprung a leak or were damaged? I'm imagining a situation like with the teslas bursting into flames when people thought that there's no way a battery vehicle could explode, but then some of them started catching on fire
