The 2017 Formula One season saw just over half the amount of overtaking as the 2016 season, according to data released by tyre supplier Pirelli.
There were 435 overtaking moves over the course of this year's 20 races compared to 866 across 21 races in 2016. That equates to an average of 41.2 overtakes per race in 2016 and just 21.8 in 2017.
Pirelli classes an overtaking manoeuvre as "one that takes place during complete flying laps (so not on the opening lap) and is then maintained all the way to the lap's finish line. Position changes due to major mechanical problems or lapping/unlapping are not counted.
