It looks like another peaceful day in San Francisco for this cyclist. Or is it? Luckily the biker was wearing a GoPro mounted on his helmet because, without that, this footage would not be available. The video shows the biker riding in the bike lane, and a van driving alongside him on his left. They both path through the intersection, and then van begins to move into the bike lane, totally disregarding the man on the bike. The tire of the bike hit the back of the van, just for reference of how close they were.
The biker reacts in the only way possible, by smacking the back of the van. It appears that he didn’t really have any other option, as it was the only way for him to communicate how close the van driver was to hitting him. The van driver did not appreciate it one bit. A man exited the vehicle and continued to berate the biker, oblivious to the fact that he was the one at fault. The cyclists remained cool and calm, reiterating to the van driver that he had caught it all on camera, as the driver verbally assaulted him. Road Rage can be a pretty dangerous thing. They are lucky nobody got hurt.
