Was driving on a deserted Mexican road and all of sudden 13-14 mustang with wide tires pulled out on the highway ahead of me. I was hoping for GT 500 but after I caught up with him I realized it was a coyote with loud exhaust. We stopped at the light and I turned my TC off, put the A6 and suspension into the sport mode. Light turned green and he took off slowly, but started going faster and louder until he gave it all he had around 40mph. I was ready for it and hit it immediately after him. Automatic transmission seamlessly shifted in 3rd and I pulled him hard about 4 cars, with his car disappearing in my rearview mirror more and more until he shut down. He followed me but never expressed any more interest.
