Is this just a track open to the public? There's quite the variety of random street cars here

@Rollin on 20s: The annual highlight is the 24 Hours Nürburgring weekend, held usually in mid-May, featuring 220 cars (from small 100 hp (75 kW) cars to 700 hp (520 kW) Turbo Porsches or 500 hp (370 kW) factory race cars built by BMW, Opel, Audi, Mercedes-Benz), over 700 drivers (amateurs and professionals), and up to 290,000 spectators.

The Nürburgring is a motorsports complex around the village of Nürburg, Rhineland-Palatinate, Germany. It is located about 70 km (43 mi) south of Cologne, and 120 km (75 mi) northwest of Frankfurt. It features a Grand Prix race track built in 1984, and a much longer old "North loop" track which was built in the 1920s around the village and medieval castle of Nürburg in the Eifel mountains. The north loop is 12.8 miles (20.8 km) long and has more than 300 meters (1,000 feet) of elevation change from its lowest to highest points. Jackie Stewart nicknamed the old track "The Green Hell," and it is widely considered to be the most demanding and difficult purpose-built racing circuit in the world.
