R&T chose a stupid title for that article. That's absolutely not what's going on in the video. The GT3 driver just wants to follow Schmitz in her BMW. Any time Schmitz gets some distance between her and the Porsche (traffic), the driver closes the gap in seconds. That guy in his Porsche is so much faster than Sabine in her BMW.
I wonder how old that video is? E39 Ring Taxi.
