Bees don't understand the concept of car ownership, so when their queen decides to hitch a ride inside a car the rest of the colony goes along for the ride, whether the car's owner likes it or not.
But their bee-fuddlement usually ends when the queen frees herself from the car so the colony can go on its merry way to a more suitable hive, usually within a few hours or at most overnight.
But Carol Howarth of Haverfordwest, Wales came back to her car after shopping and found the rear covered with bees, and the swarm followed her car for two days.
A team of three beekeepers, a national park ranger and a few passersby were able to box up the bees without killing them, but to Carol's amazement the swarm returned later that same day so she called the team in once again.
The swarm was made up of an estimated 20,000 bees, and yet no queen was ever found so it's unclear why the bees were so intent on swarming all over Carol's car. Maybe they're sweet on her?
