Discription of Events: 6/25/2018 - Tailgating a driver on West 8th Street, very angry they are going the speed limited; then they while turning onto Washington made a obscene gesture and went away speeding. Encountered same vehicle on North Main heading out of the city towards I-86; speeding, then speed up to try to beat the red light at Kingsbury Street. On the corner was a family with children and if that child stepped out when the light turned red so they could cross the road he would of most likely hit them.
