I'm sorry, did you reply to the wrong comment? I'm trying to understand where "illegitimate car rental codes" comes from here, as I never mentioned that or anything related to it.
I agree with you, just trying to understand how it's connected to what I wrote initially.
If you use a discount code, say the Boeing discount code when you rent at Seattle Airport, Hertz will cancel any insurance off the price because Boeing covers those risks itself for its employees. But, if you’re not a Boeing employee and you crash, you’re not insured by Boeing and you’re not insured by Hertz.
