I suck at tailing

When I left the house this morning, the van wasn't there. I went to my car and when I was about to leave, it turned into the street. I took the opportunity to get a closer look. I turned around myself so I could drive by while it was parked. I didn't see anyone getting in or out, nor did I get a good view of the driver. After a bend in the road I turned around again. The van had left but I could see it in the distance, turning onto the main road.

I hurried to catch up with it. Damn those speed bumps! When I reached the main road I had to wait for another car to pass before I could continue following the van. But that car was so slow I lost track of the van! Then the slow car took a left turn. I saw some lights in the distance but couldn't discern the shape of the vehicle. I took a gamble and sped up. Yes, it was the van!

I followed it for a while until it parked again. I drove by it and after a bend in the road I turned around again, but the van had already gone. I thought it might have gone toward the freeway, so hurried over there but I didn't see it anymore.
