I was going west on Armitage through the intersection at Humboldt. A woman driving an eastbound car turned left. Had I not hit my brakes, we would have collided. She saw me at the last minute and hit her brakes, but not enough to stop. As she drove past me, I saw that she was holding her phone up at the steering wheel level.
Suggested improvements for this location: This appears to be a classic example of a driver too engrossed in her phone to pay attention to the road. Clearly the current level of enforcement and penalties is insufficient to deter drivers from flagrantly violating the laws about cell phone usage.
