Javy,

One other thing to consider is what happens if driving you accidentally rip/break the end of the co2/scuba tank?

With C02, since it's a liquid, it will simply evaporate slowly. With a scuba tank you've just fire a russian roulette mechanism.



I don't know where you got this information Ray, but it is completely wrong. If you would happen to break a CO2 tank, it would be like an explosion inside the vehicle. The tank is under tremendous pressure and if it breaks, all that pressure is coming out like an explosion.
And CO2 is used for fire extinguishers for a reason, it sucks all the oxygen out of the immediate area. So, it would suck all the O2 out of the vehicle in a second.
Of course it is highly unlikely that you would "break open" a CO2 tank. But, in an accident, it is quite possible that you could knock the valve body off the tank. This will turn the CO2 tank into a missle unless it is secured VERY, VERY well. If not secured, it could very well kill you.

Two MRI's and a CAT scan....it's confirmed. I'm just not right in the head.
