No, credit card automatic policies do not cover even top 10 issues that you would have in event of an accident - they at most cover loss of revenue provision and some of the damage to the vehicle you are renting.
The only reasonable insurance that you can get is Amex premium insurance which is $25/trip (not a day) and covers everything.
Edit: Over years I tried Citi, HSBC, BOA, Chase and even CapOne "premium insurances" - they all were garbage with a list of exclusions longer than most of TOS policies on shady websites.
It is illegal to sell insurance by non-licensed sales people - see Zenefits. It is illegal to claim that something is insurance or describe it as insurance when it is not. If paperwork says it is "waiver" but someone who makes me sign for it says it is "insurance" they are committing a crime and if a company actively encourages such behavior the company is engaging in a criminal activity
Insurance, waiver, whatever, it will save your ass if you purchase it when you need it and one should seriously understand whether they need it or not. It's that value that makes me question whether one should call it a scam.
If you fall asleep and drive a car into a house or hit a pedestrian, you better have to have some third party liability coverage. If you have car insurance already you probably have this coverage, but if you don't... you don't.
This is a pretty complicated topic and I've done some deep dives into it and found it's not as clear cut as most people seem to believe. What kind of card you have matters, whether you have insurance already matters and even with both of those you need to understand what exactly is covered by who and when. If you don't have insurance you should always get liability. If you don't have insurance and rent a lot you should call up Progressive or National and request a quote for non-owner liability coverage.
What one shouldn't do is go around telling people to waive all coverage and that rental car insurance is a scam.
This is much more than the cost to the consumer of renting the car. How can they possibly defend it?
That's problematic if you don't have insurance, or if you are in a risk category where some accident or damage to a vehicle will result in policy cancellation or a rate hike with your personal insurance. Some personal policies have different limits or gotchas for incidents related to business travel as well.
If you have a standard auto policy for a vehicle at home, you should also check whether it covers rentals. A lot of policies will cover you while driving "non-owned" vehicles for personal use with the same coverage limits/deductibles as your own vehicle.
I don't think sarcasm helps having a productive conversation.
Also, straw-man: I wasn't arguing we should strangle anything.
Regarding the rest, it sounds like they got used to offering a poor service because they don't have enough competition or something. You might have a point there, but for a competitor to take advantage of that they just need to execute better on those points. They don't really need to source their cars from average Joes...
I'm not saying that Hertz isn't shit, I'm just saying that I don't understand how where the cars are sourced from is a real differentiating point. EDIT: I just re-read your last line and it seems you agree.
