Video Summary

Five cars participated in a race and received points whenever one car overtook another. The goal was to determine the minimum points awarded based on the cars' start and finish positions. Initially, cars 3 and 5 were ahead of car 1, but ended up behind it, requiring car 1 to pass both. Car 2 had to overtake cars 3, 4, and 5. Car 3 ended last, overtaking none. Car 4 passed car 5 as it finished ahead. Thus, 6 overtakes occurred in total. Therefore, the smallest number of awarded points is 6. The answer is 6.
