Anecdotally, I have personally witnessed an incomprehensible rise in the amount of motor vehicle crashes in the past 15 years and the single greatest contributing factor seems to be smartphone distraction.

Just last fall I responded to a late-night crash where a drunk driver lost control and pinballed across the highway hitting both barriers and coming to a rest on the shoulder when a second vehicle whose driver was looking at their phone failed to notice the gigantic fire engine with flashing lights blocking the right lane of the three-lane road and braked just late enough to crash into our engine.

We found the phone, still playing a video, in the driver's side footwell.
