The cops are the ones investigating, and I'm sure the number of actually stolen rental cars is far greater and comes along with identity theft. But at Hertz some human should do a thorough check.
The person who didn't. You can't set up a system like this and have no personal accountability. Can't find a person who is responsible, the CEO will do nicely. A lot of games would smarten up if the CEO went to jail for this kind of human-less "system failure." A corporation is its people. The people are responsible for committing crimes. Refusing to check should not be any kind of defence.
In Australia, there are company registered cars. If it runs a speed camera, the company must either pay a lot or cough up the "guilty" party who would pay less but get demerits too.
The Australian solution to Hertz is give out company fines until they produce who did the false report.
No need to go after the CEO or related. It's not like Hertz is suddenly going bankrupt to dodge the pitful fines.
If the potential damage is more than the company can afford, then by all means, they should go after those running the company.
