I decided that I wanted to change my diaper while on the road, and so I decided I would give it a try. I pulled off to the side of the road on a 65MPH Highway, the car was on a slant, so I was a little lower than than normal, and I changed my diaper from the driver seat. As far as I could tell, there would have been no reasonable way for anybody to tell. My back windows are tinted, so they would have to look at me right as they passed, and anybody approaching from in front would not be able to see because of my steering wheel and dash. It was actually surprisingly easy to take care of that way, and since it was kinda in the middle of nowhere, I wasn't too afraid of being noticed.
