Discription of Events: In bumper to bumper traffic, they sped past me and then cut in front of me. When I would get close to them they turned on their windshield wipers and sprayed the fluid in an attempt to cover my windshield with the spray and block my vision. I was behind them for about 10 miles and they continued to swerve in and out of lanes and any time I got close (due to just how the traffic flow was) they would spray their windshield fluid. They also would tailgate the people in front of them.
