NOTE: Full version of this Notebook is at Kaggle.

This notebook visualizes race traces for every F1 Grand Prix in 2018, using historical data from the Formula 1 Race Data dataset (provided by ergast.com and updated on Kaggle after every race), along with race event information from Wikipedia.

Race traces are a great way to capture the dynamics of a Grand Prix. They show the gaps between cars, how the field spreads out over time, and the relative pace of each car as the race progresses. These traces are based on cumulative lap times, adjusted using the median lap time at each point in the race. The horizontal zero line serves as a reference for a virtual car running at the field’s median average lap time—cars above this line are faster, while those below are slower.

Here are some key features of the race traces:

• The line colors for each driver are based on their team colors.
• The fastest lap is marked with a ★.
• Laps where a car went via the pit lane are marked with a ●.
• Laps affected by the safety car are highlighted in yellow, indicating why the gaps between cars have reduced.
• Virtual safety cars, introduced in 2015, are highlighted in orange, as they cause the lines to spread out temporarily since leaders have completed more of the first affected lap at racing speeds.
• Overtakes are visible where the lines cross, often due to pit-stops.
• Truncated lines indicate retirement from the race.

The shadow at the bottom of the trace indicates which cars have been lapped by the lead car. This helps to reveal some effects, such as leaders making pit-stops to avoid slower traffic ahead. Backmarkers must allow leading cars through, and the edge of the shadow shows why their lines suddenly dip. Leaders may also ease off to let a lapped car through at the end of a race.

It's worth noting that good safety car data is hard to find, and the data scraped from Wikipedia may contain some mistakes. Therefore, the virtual safety car highlights in the traces are the author's estimates using lap-time data.

Overall, these race traces offer a comprehensive and informative way to understand the progress of each F1 race in 2018.

2018 Formula One World Championship¶

For background see Wikipedia; here's an excerpt:

The 2018 FIA Formula One World Championship was the motor racing championship for Formula One cars and the 69th running of the Formula One World Championship. Formula One is recognised by the governing body of international motorsport, the Fédération Internationale de l'Automobile (FIA), as the highest class of competition for open-wheel racing cars. Drivers and teams competed in twenty-one Grands Prix for the World Drivers' and World Constructors' championship titles.

The season was, for the second consecutive year, a title battle between Mercedes and Ferrari. The 2018 season saw two four-time World Champions, Lewis Hamilton and Sebastian Vettel, as the main Championship challengers. It was the first time in Formula One history, two quadruple world champions would be competing for a fifth title and the season was billed as the Fight for Five by journalists and fans. The championship lead ebbed and flowed between the two title contenders, the points lead swapping hands five times throughout the year. At the halfway point after the British Grand Prix, Vettel led the title battle by an eight points. Hamilton clinched his fifth World Drivers' Championship title at the 2018 Mexican Grand Prix, with the team securing its fifth consecutive World Constructors' Championship title at the following race. Ferrari driver Sebastian Vettel finished runner-up, 88 points behind Hamilton, with his teammate Kimi Räikkönen finishing third. In the Constructors' Championship, Mercedes finished 84 points ahead of Ferrari, with Red Bull Racing-TAG Heuer in third, 152 points behind Ferrari.

In 2018, the championship saw the introduction of a new cockpit protection device, known as the "halo". The introduction of the halo was the first stage of a planned rollout that would see the device adopted in all FIA-sanctioned open wheel series by 2020.
