Okay, maybe I didn't pass this particular Ferrari, but Jay will corroborate that I did in fact pass at least one Ferrari.
Here you can see the sand that was laid down between Kallenhard and Exmühle in an attempt to clean up the diesel that had been spilt along the track during a crash the previous day. The sand was also a reminder that the Nürburgring is, in fact, a public toll road, and that posted speed limits must be obeyed. This was the only stretch while we were there that a speed limit was posted, dropping us down to around 50 kph or so.
A fortunate consequence of the crash and resulting slippery section is that motorcycles were not allowed on the track this day. Motorcycles and cars do not get along well, particularly on racetracks. Cars accelerate slowly but corner quickly, whereas motorcycles accelerate very quickly (less mass) but are slow to corner (fewer tires). The result is that the motorcycle that passes you after the last corner is the same one you're barreling down on as it slows down for the next corner. We didn't have to worry about that back-and-forth.
