Some background info: I walk every day to and from college. I play trombone in the band and I've rented a French horn to learn, which means every Monday and Wednesday I carry a trombone on my right shoulder with my hand to secure the strap (case has backpack straps and I use one since I have an actual backpack too) and the horn in my left. Now, I know this light. If you don't press the button button before the light turns green, even if it's a half second late, the hand doesn't turn into the green walking guy, but the light still will be green for over a minute. I get to the light right as it turns green, and obviously my hands are full so there's no realistic chance of me pressing the button. I look both ways and walk. Then, I hear a loud engine and someone laying into their horn. I turn to see this speeding black car racing towards me and slightly drifting towards the curb but not signaling. Given that I just walked past a bar, I take a couple steps back to position the light pole thing between myself and the car ( I only had taken a couple steps into the crosswalk) as a precaution. The driver slams his break in the middle of the crosswalk, makes an angry gesture towards the red hand, drives extra slowly until he's out of the crosswalk, and then zips away. Now this confused me because whenever I drive, I always look for pedestrians, light or no light. I get that the walk signal is somewhat for my safety but do drivers really rely so heavily on it?

TL;DR I walked technically on a red light even though the traffic light would stay green for a long time, angry driver honks at me
