I had someone park in my driveway while I was away for the night. I was just moving into the place, a complex with both apartments and townhomes where everyone had numbered, dedicated parking spots or driveways. I had a carload full of stuff and this car was blocking my (single car) driveway and garage. I had to park across the opening, partly because there was no other space available and partly to make sure the car's owners had to get ME to move. Since I was new, I asked the neighbors on either side, no one claimed the car or recognized it.
So, 5 hours later I'd had enough and went to the apartment office. They gave me the local tow company's name, I called, and the truck showed up. After clarifying with the driver what car to tow and moving mine out of the way, he was preparing to do so. Magically, the car's owner came sprinting across the roadway from a townhouse across the street! I guess she had been watching and hoping I would just drive away so she could sneak off in her car. She begged me to call off the tow driver and I told her it was now her issue. She did manage to avoid getting towed, but if not that would have come with pretty steep tow and impound fees, all owed by the car's owner.
SS single driver in the HOV/carpool lane - it's not often I see the state patrol enforce this, but yesterday while the rest of us were sitting in stop and go traffic, we all got to see the patrol swing into action and take down the large pickup who had belatedly noticed the marked SUV and tried to merge back into the regular lanes. That's a $283 fine, I believe.
