Right, but he's also in a 5K pound vehicle. A virtual tank. I drive a BMW X5 with runflats. Unless they break the glass, no one is getting inside. That thing's a tank. Puncture the tires? It's good for another 50 miles. These bikers come out every now and then (usually for parades or other ethnic events). It's best to just let them do their thing if you're in a tank of a car. Otherwise, people will get hurt.
From the video, I did not see anyone try to break his glass until after he ran over some of them and their bikes. Those were motorcycles, he could've gotten out of there slowly. Him speeding off is what lead to this guy being in the hospital. He over-reacted.
If he rolled down his window and told one of them that his family was in the car I am sure they would've let him go. Did he have to do that? Of course not but sometimes it's just better to diffuse a situation than escalate it. These bikers may appear dangerous but all it takes is some communication to lower the tension instead of treating it like a siege...
