Also consider, just because someone thinks something is unsafe does not mean it is true. We could go forever saying things are unsafe, they may or may not be. Actually, I think most things are unsafe, just a matter of how unsafe. I see city buses with propane tanks on top. That has to be unsafe. If the tank ruptures, gas will go into the bus.

There are varying degrees in a case like this. Is having a plastic jug of gasoline secured to the back of a vehicle by bungee cords as safe as hauling it in another location that would not be hit in a rear end collision?
Auto makers would certainly say it is not and that's why they protect tanks in cars even though they are near the back of the vehicle.
My point is simply that there are much safer locations to store fuel - and on the flip side, there isn't a more dangerous place.
