I got follow today!

When I was driving home today. I notice a car was following me. I step on my gas to go faster. The car was right behind me wtf. I check to make sure my car doors was lock. I stop at a red light and the car behind me pull up next to me. Their was 2 guys in the car. They was trying to get my attention to roll down the windows. There was no cars behind me and the other car. Lucky i saw another car pull up. I roll my window down a little. I ask him what does he what. He told me i have a flat. He said he help me fix it. I said no thanks. I speed off. I know i didn't have a flat cause i would of felt it driving. There was no way i was going to pull over. It was dark not to much lights. There was no one walking around. I'm not going to fall for that trick. When I speed off the car was still behind me. I stop signaling. I just made the turns to make sure they weren't following. They were right behind me crap. I drove all the way to the belt. That's the only way I'm going to lose them is on the hwy. If i didn't I'm going to have to pull into a police station. I didnt see a front license plate. I finally lost them 35 mins wasted. I was still driving in circles to make sure. When I finally got home i check my tires. I didn't have a flat!!! They must of thought i was a easy target Stupid assholes. How do I avoided suitation like this?
