**Special version for end of F1 2016. Olympic rank + Simulate scoring system**
- What would happen if the 10-point scoring system was used? Would the
champion be the same? This version will give you the answer.
- **Olympic rank:** Alternative rank with the gold first method. The driver
with superior race results (based on descending order, from number of
wins to numbers of second-places down) will gain precedence.
- **Road to championship:** When the season goes down, we can calculate who
would be the champion predicting the results in the last races.
Olympic rank is counted in case of points tie. Rosberg or Hamilton?
