Milka was totally holding her back by blocking her way even though her car was just plain slower than Danica's. For anyone not familiar, in most open-wheel racing circuits, if you are driving a slower car and are in the back of the pack during the race (like Milka was at the time), and a car that IS in contention (like Danica was at the time) is coming up behind you, you are expected to give them room and allow them to pass. Milka didn't do that, she held up/impeded Danica, and Danica had every right to be pissed at her for it.
