What did the vids say? If they attack slam the gas?
I don't know what videos he watched, but I subscribe to the "motorcycle gang" dump and drive method.
There was a woman with her kid in an SUV or small cross-over. I think this was in MD, but not sure. There was a large gaggle of motorcycle riders surrounding her as she drove. Not a biker gang -- just a bunch of crotch rocket riders out for a group ride.
When they came to a light, the group started showing off with wheelies and other stunts as they waited on the light. But, after the light changed, the group was still blocking traffic. So, the woman honked her horn.
The group started moving, but then one bike in particular started harassing the woman. Driving in front, brake checking her, getting on her rear bumper .... anything he could think of to piss her off. At the next light, she stopped, and the group tried circling her again, and the harasser got OFF his bike and started yelling at her through the closed windows. She hit the gas and ran over a few bikes, and I think she hit the harasser, though he was not too badly injured.
That really escalated things. The woman was now being pursued by 100 bikes as she tried to speed away. She called 911 on her phone to report the incident, and then drove to the nearest highway patrol station -- bikers in tow.
Nothing ever happened to her. As long you can say you feared for your life/safety, trying to flee and go to a law enforcement office is a reasonable response. Having a piece of glass between you and a bunch of bike riders hitting your vehicle with helmets is not a valid argument for sitting still and hoping they go away.
