When I was in New Zealand in 2017, I rented an SUV for two weeks. Except I unknowingly screwed up the reservation and only booked one week, driving off unaware of this problem. So about a week later they began trying to call my cell, but didn't get through because I switched SIMs. I proceeded to drive around New Zealand with no problems for the next week, blissfully unaware. On the day before returning my car, I got pulled over for being over the speed limit. The cop let me off with a warning. It wasn't until I got back to return the rental that I realize that I was a full week late. Whoops.

Thank God it wasn't America, apparently.
