After hearing stories of airport attendants adding miles to parked cars, what do you do to make sure it doesn’t happen to you? Or at least keep track of your car’s activities while you're away.
I hadn't really thought about it before, but since you mentioned it, I took a look. I had a similar "park and fly" situation at Cincinnati/Northern Kentucky International Airport from the 10th to the 17th last month, and it correctly didn't register any trips during that period. So, it looks like it's working as it should.
I usually take a picture of my car’s odometer before I leave and when I pick it up, just to be safe. It’s a simple way to keep track of any mileage discrepancies!
