Video Summary

The problem involves determining the number of cars containing exactly 2 people, given there are 8 cars with either 2 or 3 people each and a total of 19 people. The solution involves a guess-and-check method, testing various combinations of cars with 2 and 3 people. After several iterations, it's found that having 5 cars with 2 people accounts correctly for 10 people, leaving 3 cars with 3 people to account for the remaining 9 people. This totals to 19 people. Therefore, the answer is that there are 5 cars with 2 people each.
