"Because of its flammability, it is illegal to replace R-12 with HC-12a in the United States."
Probably as a result of lobbying by the makers of R134a. "HC-12a is also patent-free due to its non-synthetic nature." (Wikipedia) It's a blend of propane and butane.

Has thee been any instances of vehicles going up in flames in other nations that allow R12a? Isn't gasoline flammable? How about propane? Yet, there are plenty of vehicles on the road using them.

BTW, R134a isn't as efficient as R12a and though it isn't an ozone depleting gas, it is a greenhouse gas that should be phased out.
