I’m a school bus driver and I used to use my high vantage point to count how many passing drivers were looking at their phones instead of ahead of them, and I estimated that it was about 1 in 4. I even had a cop pass me while I had my lights on and kids were about the cross - he was face down in his phone and driving with one hand.
I stopped counting for the sake of my mental health. I truly don’t understand why I don’t see multiple collisions a day because of this shit.
