Are there any real life instances of aircraft aborting a takeoff or landing to avoid a vehicle? I came across a fake video of an A380 closely avoiding a fuel truck. More details at Snopes including a link to the YouTube video.

While this video is not real, I'm interested in finding out if it's a realistic situation and if there are any real instances where accidents have been avoided because crew decided to abort takeoff or landing as a result of an unexpected runway intrusion as seen in the video.
Not only is it possible but it happens. This is formally called a "runway incursion" and it does happen like 2005 Logan Airport runway incursion or the B733 / vehicle, Amsterdam Netherlands, 2010. Skybrary has a full list you can find here which is quite lengthy and includes a full section for Vehicle Incursion.
