Typical local news ratings-grab stunt. All hydrocarbon refrigerants are
odorized, just like the LPG in your barbecue tank and the NG in your home
gas lines, for that very reason. There's no way you could STAND to be in the
car until an explosive fuel air ratio was reached.  You could just as easily
blow yourself up leaving the stove on in a westy. Propane there too, a lot
more than 18oz of it, and it's contained in a system DESIGNED to vent freely
into the interior-- no need for a production assistant to puncture anything.
Every refrigerator sold in Germany uses hydrocarbon refrigerant.  Like
anywhere else, safety with HC chillers is a matter of maintenance and
caution. Sure, it has the potential to be a greater fire hazard than R134a,
but so does gasoline over diesel. Life's a series of calculated risks.
