Entitled Driver Close Pass

We were riding in a group of 3 coming up to an intersection to turn right. This driver in this ute decided they would race us to the intersection and stop. We're very unsure what she gained from this as we didn't slow her down at all and she came dangerously close to us. She then stopped further up the road and was recording us, we're still unsure why this was. Very strange deranged person.
