This happened in Baltimore city around 3pm. The speed limit in this area is between 25mph and 40mph and he flies past me as I start to head through a green light and merges into my lane while traveling through the intersection and nearly hits me. I had to slam on my breaks otherwise he would’ve caused an accident. After nearly hitting me he sat at a green light since he was not paying attention to the road and it was not until beeping started that he kept driving.
