Apparently avoidable contact can still be called without any actual contact...
48.3. AVOIDABLE CONTACT. Any Driver who, in the sole opinion of the Race Director, initiates
avoidable contact with another competitor, whether or not such contact interrupts the other competitor's lap times, trac position or damages other competitor's Cars, and whether or not such actions result in actual contact, may be warner or penalized pursuant to Art. 60 of the RULES. In accordance with Art. 62.2.1.B any action or decision (or alleged inaction or non-decision) taken by or imposed by the Race Director, Supervisory Officials or IMSA Officials in this regard is Conclusive.
Easily the dumbest rule to exist in anything ever.
