Very Strange

It was the morning commute, approaching the toll plaza of the Bay Bridge heading to San Francisco. The approach was completely backed up and the cars were moving at a snails pace. I was carefully splitting between two lanes. Looking ahead I noticed a six wheeled pick-up, it was blue. I saw that the driver and the passenger were looking at me and sure enough the driver blocked my path. There was a fellow rider behind me. Thankfully the driver to my right moved to the right to give us some room. When I approached the passenger side window the guy rolled down his window and flashing a badge, told me to get behind him and that what I was doing was illegal. I told him that what I was doing was legal. As I was saying this he reached behind him. I was spooked and was not too sure what he was going to pull out next so I just took off. Very strange!
