Driver cut me off slammed on breaks and proceeded to flip me off ,also kept on harassing me as I went on the hyway a few miles later

drives with no muffler, loud enough to set off car alarms as he passes by, street is only 25 mph yet he goes full throttle, 40 mph, 50 mph, he uses south 5th ave as his own personal race track, terrorizes the whole neighborhood!!! goes back and forth all afternoon, cruising, in a big hurry to get nowhere, weird how he never travels anywhere, hes either unemployed, or is he on parole? ankle bracelet, etc. where he cannot go very far, i dont know, but he is a real nuisance, plus he is reckless driving in other vehicles too, spinning tires, etc…he never wears a helmet, and ive seen him give rides to his kids, the kids had no safety gear on, last summer, he had a 4 yr. old girl, with no shoes on, thats the most dangerous thing ive seen a parent do to a child !!! now ive complained to the landlord, no action, ive complained to the police, again, no action, why is this guy still allowed to get away with this? if it were anyone else, youd be in handcuffs, but this guy seems
