18. Lewis Hamilton vs. Nico Rosberg
Formula One has served up some outstanding rivalries and this is one of the best in recent history. The UK’s Hamilton and Germany’s Rosberg were both driving for Mercedes but that didn’t stop them from wanting to beat each other. Hamilton won two championships and Rosberg one during their time together.
But this rivalry was fiery. The final season, when Rosberg won, saw them crash out of races together and infuriate their bosses who threatened them with team orders. In the final race, Hamilton tried to let rival drivers overtake him and Rosberg so that he would finish with more points. They just never saw eye-to-eye.
