I was thinking the same thing.  That sounds like a super bad idea.  What 
happens if you're welding this thin sheet metal and blow a hole through 
it and the gas starts leaking out?!

As far as the "explosive gas" I guess you mean CO?  Any car with a 
properly functioning fuel injection and catalytic converter(s) should 
have nearly zero CO content;  ditto for unburned gas or oxygen.  So if 
you're ever in the mood to kill yourself, don't do the old "car in the 
closed garage" trick.  It don't work anymore!
