We suspect that this picture must have come from Britain - there's something very British about the sarcastic, demeaning tone that's been taken in lecturing this parking offender! We don't get to see their car to scale, so we have to take the author at their word, but it's not hard to understand why they'd be so upset.
If you have a small car, parking should be easy for you. There's plenty of space between the lines, and maneuvering into it shouldn't be a worry. Parking across two lines once - on a bad day - might be just about understandable. To do it regularly just tells everyone that you don't know how to park your car. When that happens, you find yourself winning prize certificates like this one, written by someone who's politely reached the limits of their patience.
