Driving on the 101 southbound this car slwoed down and refused to let us pass. He then kept getting in front of us to slow down. There were 2 men in the car. They at one point cut across 3 lanes of traffic to cut me and my family off. Very dangerous and very reckless. Finally we were able to pass them and they slowed down next to us and tried to get our attention. We didnt engage. Be careful of these "men" they dont have any regard for the human life and could have seriously hurt me and my family. Be on the lookout.
