(Mildly) amusing anecdote from 1997: I rented a small car for the purpose of a working trip to the Bonneville Salt Flats in Utah. The rental clerk told me I was limited to California and Nevada, unless I paid more. Well, Bonneville is five miles past Nevada.
During my week at Bonneville the racing was interrupted by rain, so I drove to Salt Lake City to have my film developed, to verify that my exposures were good. While parked in SLC, the car was ticketed for having expired license, while I and others watched from the doorstep of the photo lab. I promptly dropped the ticket in the nearest waste basket as if it were simply MOOP -- much to the amusement of the others present.
And I never heard a word from the rental company, even when I rented from them again.
These days though, as mentioned above, rental cars tend to have "secret" GPS onboard.
But I expect that Nevada is still generally considered a part of California for this purpose, since so many Californians go to Reno and Las Vegas for gambling.
