I was stopped behind a school bus, and about half a dozen other cars.
She was looking at a cell phone. I know for a fact because after I climbed out the passenger side of my truck, I went and opened the door of her car to see if she was ok. There she sat holding her cellphone, a state of shock.
Without those airbags we would have one less distracted driver on the road. I would like to say that’s “the hard way” of getting people off their phones while in the car, but frankly it’s probably easier then convincing people that it can wait.
