Wow, what a jerk! And your dashcam footage shows this assbag illegally turning left WHILE a pedestrian is in the crosswalk. Hopefully this person gets diarrhea while on the way to an important event.
It's the Law in NY that you must stop for a school bus with red lights flashing. This lady was 100 feet away when red lights showed up. There was no way to miss them. She just kept driving. The fact that such drivers don't pay attention when they drive can cause tragedy of any form.
This reckless driver has already killed an 85 year old coming out of his driveway: https://nyc.streetsblog.org/2020/02/03/brooklyn-da-let-killer-driver-off-the-hook-for-no-reason/
