It doesn't matter. The massive explosions causing loss of life and millions of dollars in property damage are nothing compared to the .000000000000002 deadly atoms of C02 your SUV emits into the precious atmosphere.
Just deal with it- it is for the common good, jeez.

OK, I'll fill two big plastic containers of equal volume, one with hydrogen and one with gasoline. I'll strap an igniter circuit to each that will guarantee that they will each blow up. You and I each take one. I'll take the hydrogen.
Where would you like me to send your "crispy critter" corpse? I'll be able to do that since I will be alive and you will a charcoal briquette (and unfortunately I've seen what a "crispy critter" looks like and had to deal with it in a previous job as an ambulance driver).
The image of hydrogen being this big nasty explosive problem as compared to "safe" gasoline is a dangerous and foolish misconception. How (and why) do you think most "crispy critters" get crispy?
Most people point to the Hindenburg (as several people in this thread have done) to "prove" the dangers of hydrogen. Well, guess what? It wasn't the hydrogen you saw burning in the old newsreel. It was the aluminum based doping compound used in the skin. The hydrogen flames were virtually invisible in that film.
And specifically examining the Hindenburg crash, there were 97 passenger and crew on the Hindenburg when it burned. 62 survived. That's a 64% survival rate. When's the last time you heard of a plane crash with a 64% survival rate?
Hydrogen ain't the problem. Doing dumb things with any combustible material is the dumb thing.
Me? I favor Hydrazine and a little "agenothree." Hypergolic chemicals are fun and potent, but they are not our friends!
