I'd say...

• Being disproportionately angry over nothing. Being irrational in that way and many others. The uncertainty that brings introduces great threat.
• There being more than one of them all chiming in with the possibility of that number growing. They're in effect hovering around / surrounding and crowding out the couple.
• Threats of physical violence. Several racist elements to their verbal assaults also embodied in the threats of violence.
• The car is pulling back way too slowly to have any intent of hitting anyone and stops. That the car was trying to hit her is incredulous. It crawled to just within arms reach at best. That was it.
• The couple makes every effort to be reasonable but as is their right they do not submit or concede to accusations or demands made of them neither or which they're legally obliged to follow and it would be a violation against them if that were expected.
• When the car stops, the woman hits it as hard as she can making a loud aggressive noise very much giving the impression of the car being under attack.
• Pedestrians usually have the right of way within reason. The car is not however violating that and in this situation it doesn't make sense why she didn't move out of the way or was even standing in the way like that.
• The point at which they get out she has obstructed the vehicle, violently assaulted it after making threats and is still harassing them and being hostile.
• Any normal person would be alarmed when a gun has to be pulled on them. This woman's behaviour is almost as though that's what she wanted. There's zero fear and obviously she does not believe she's in danger from the weapon. It's a huge transition from having an overreaction to a car moving very slowly that's still some distance away to then suddenly not giving a damn when having a gun pointed at her. It's just all an act, it's blatant.
• When the gun is pulled they make it very clear the reason why which is to back away so they can get away, to clear away from the vehicle. At this time they've also all rushed in and crowded her out putting her right in the middle of effectively a violent mob. When the gun is pulled, it is after she tells them to back off and when she's handling it it's very clear that it's to keep them away from her and her vehicle.
• The gun is 100% effective in the end. The daughter has to tell her mother to stay back. That gives the game up. They stay back and allow the vehicle to leave.
• The ending comment crying as though somehow victims all of a sudden saying that it's white people they're so racist is the most obvious melodrama I've ever seen. Again, it gives the game up.

The weird thing is this looks to me almost like one of those insurance scams where you falsely claim injury from car accident. I suspect if you look into this family's history that this is a way of life for them. They're probably scum and that woman should likely have her kid taken away from her given the life lessons such as fraud, perjury, etc she appears to be teaching. If they'd not pulled the hand print or the video had no just caught it then they would have made out the noise was the car hitting her in an insurance scam.
