This is a question that has irked me for ages...does adding authorized drivers to a rental contract really matter? It seems to me that as long as you didn't sign up for Hertz's additional insurance, there's no real consequence that can come from it, right? I'm assuming that if you signed up for Hertz's insurance and broke the terms of the contract, they would void your coverage, etc. I'm also assuming that any additional drivers have their own personal auto insurance. To me, it seems no different than driving a friends car with your own insurance, for example.

Sure, Hertz won't be happy with you (the renter) if something happens, but what real consequences are there as long as the additional driver was insured? Hertz

Some background- I'm so used to sharing a car with no issue between coworkers (corporate CDP allows any company employee to drive the rentals) that I think nothing of it to give somebody else my keys. Flash forward to this week where I'm renting with family and my dad is taking a hard-line stance on not even touching the keys because he's paranoid about not being on the contract, and his stance is causing all sorts of issues because I'm the only one he will allow to drive the car.

Thoughts?
