Explanation of selected testcases: The naming scheme for F1 season articles changes between 1980 (1980 Formula One season) and 1981 (1981 Formula One World Championship). So test the infobox as it appears in the two articles immediately preceding and following the change. Also test 1950, where the naming of the previous season is also different (1949 Grand Prix season).
