Your banter is all personal "op-ed" (opinion editorial).
If you possessed EMPIRICAL facts/data versus conjuring up "burning golf's" & "rear ending F-150" personal fantasies the facts/data would be applicable, your fantasies? Not so much. Please share...facts...not histrionics. I've literally never owned anything motorized/substantive/fueled (Car, Motorcycle, Moped, Snowblower, Leaf-blower) that went up in a "blaze of glory" no matter the ignition source. You have?
My "ranting' is akin to your "fantasizing". Everything/anything can be a critical safety item, no? Likelihood of your burning fantasy emanating from a 12v power source v. a taillight? Factually speaking, I suggested possible safety issues that could arise from a failed 12v power source, not a power cord or the "irresponsibility" of those using such.
Yes, I'm "honest"...thus I don't understand your "honestly suggesting"...ahh, I suggested it, thus I honestly believe it.
If I had to hypothesize, I would "imagine" that all automotive manufactures ---and the majority of aftermarket vendors--- possess rigorous standards. Imagine? Ya, I can probably get you two (2) or sixty-nine million (69,000,000) Takata Airbags "on the cheap"....and that's a FACT.
