The 17 mile long race track in Germany has a webcam that I’ve never posted to Automotivation. I’ve seen some great cars on it including Porsche 911 GT3 RS’s, Viper Competition Coupes, Ferrari F430’s, and more. Have a look for yourself:
It updates every minute and requires you to manually refresh it. Remember, it’s in Germany so they’ll be racing when it’s dark over here in the states.
