I don’t buy the distraction numbers. I see people on their phones constantly while driving, despite laws against it. It’s also impossible to really prove anything after the fact, as the article touches on. The graph shows a massive increase in “distraction not reported,” which to me just sounds like the driver didn’t choose to incriminate themself.
The spike started in 2010, which is when 4G was rolling out, Instagram launched, Facebook was already big, and social media in your pocket was becoming an addictive reality. Before this, there wasn’t a lot to do on a smartphone while driving.
