The Crew - Indy Car Racer - Drive 200 laps around the Little Eagle Speedrome in total. [Silver / 100G]

The "Little Eagle Speedrome" can be found in the south-east of Chicago (near St. Lous). It's an oval race track and is marked on the map. You have to drive 200 complete laps on the race track (asphalt street) in the Speedrome. You should wait with this till later in the game when you have a fast car. The Koenigsegg Agera R is the fastest car in the game. In this video the full stock RUF CTR-3 (without any upgrades) was used, which is the second fastest car in the game. Each lap is 2,8 miles (4,5km) long and takes around 45 seconds. So if all goes perfectly this will take 2,5 - 3 hours to complete.
You can view your progress by opening the world map, then press the left stick and go to the "Awards" tab. Now choose "Zones" (in the Explore category) - "Midwest" - "Indy Car Racer" (second symbol in the first row).
