In what way is the U turn illegal?
Why were you riding in the door zone?
Why did you not moderate your speed when taking an exposed position both in the door zone and near the crown of the road?
Considering the number of motor vehicles around, and the inherent danger in the maneuver in which you engaged, why was your head glued straight ahead? Dreadful observation skills.
And why the tourettes? You have no knowledge of the occupants of that car or their propensity to react violently .
The car driver really was very naughty and should have used their mirrors. However, a safe and competent cyclist should be anticipating such opportunities for danger, yet you chose to fling yourself head long towards without slowing and without proper obs instead. There is a salutory lesson there for both of you.
If you report it to the police you might want to remove the S4a POA soundtrack first.
