It has infrastructure problems but Toyota's fuel cell vehicle is feasible.
Excluding catastrophic tank failure I don't think hydrogen would be more
of a problem than  propane.

Typical propane tank pressure: 100-200psi [1]

Typical hydrogen tank pressure (for cars): 350 - 700bar which is 5,000
- 10,000 psi [2]

A 5k to 10k psi tank rupture will impart much more kinetic energy into
the shrapnel thrown off than a 100-200 psi tank rupture will impart. 
And that ignores the impact of the pressure wave created by the
decompression of the stored gas itself.
