So, that's interesting. I pulled statistics for my state, and it bears out what you're saying. In 2010, there was about one reported accident per 478,873 miles. In 2000, 405,000. In 1990, 378,000. And way back in 1960, when I'm sure no one had a cell phone, one in every 313,000.
Is it possible that cell phone use is increasing accident rates but something else is lowering it? Sure, it's possible, but that's just guesswork. Somebody needs to dive deeper into the data to figure it out. Maybe people used to drink and drive more. My data source for alcohol involved crashes only goes back to the mid 2000s. Personally, I almost hit someone because I was messing around with my phone. I learned my lesson. I had some idiot 20something total my car with my kids in it because he was, by his own admission, fishing around on the floor for a CD. You're right, I don't care why you're distracted. Knock it off. Pay attention. My own experience tells me I'm a worse driver if I use my phone. I've heard of plenty of studies that report the same thing. It's also intuitive. If you're not actually looking at the road, it's hard to avoid hitting things.
