After several near death experiences in daylight crossing with a green light in a crosswalk from left turning cars and a city bus across four lane arterial road

After several near death experiences in daylight crossing with a green light in a crosswalk from left turning cars and a city bus across four lane arterial roads, I now have a high intensity blinking flashlight that I aim at the driver. I suspect that these drivers are NOT looking across the entire crosswalk and are focusing their attention on oncoming traffic. In the case of North American city buses, the low mounted side mirrors block view of pedestrians and pedestrian fatalities are frequent because of this. In Europe the side mirrors are mounted from the roof allowing visibility of pedestrians.
