Anything can happen

Today I came across something interesting and unusual. As I was headed to lunch at mom's house, I noticed a van in front of me with the front passenger door partially open. The passenger had his right foot on the rocker panel and his right hand was holding the door open. Since I'm not in a marked police unit, I couldn't initiate the traffic stop. I didn't know what the passenger's intentions were. I thought maybe he was about to jump out of the moving vehicle!  I got on the radio and started calling for a marked unit to assist. I followed the van several blocks before it finally pulled off the road and parked at a residence. I got out of my vehicle and motioned for the passenger to approach the front of my vehicle. The occupants turned out to be an older couple. When I asked the gentleman if he had a reason for riding with his door open, he stated, "I was hot." I then reworded my question and asked if he had a "good" reason for riding with his door open. Then he explained that he was returning home from dialysis and the a/c didn't work and he couldn't roll down the window. I then gave him other alternatives when faced with the same problem later. One was maybe try pulling over and finding some shade for a minute or going to a store with a/c. Before you ask, No I didn't write them a ticket!
