The guys who swerved claimed he had to doit cause he was gonna hit the car in front of him. I didn't think he was close enough for that kind of reaction. But then again the lens angle is distorted, so it might have been. he obviously wasn't very aware of his suroundings, cuase he did swerve with no regard for what was around him. It was the girls missfortune, and he was lucky it wasn't a semi truck. He would have been crushed.
He shouldn't have swerved anyway, would have slowed down faster if he hadn't. But I wasn't driving, so I could be wrong.
If people don't regulate themselves, others will do it for them.
