I think as long as people are driving, there will always be error. I totally agree cell phones are probably the worst offender, but I've seen all sort of other crazy things. Girls doing their makeup, guys stuffing double-cheeseburgers in their mouth with fries on the dash, somebody's dog jumping from seat to seat, you name it. I had a friend in the late 90s go to get a CD out of one of those 100 disc CD books (remember those? lol) and it fell off his front seat. While he was fumbling to retrieve it, he hit a parked car on the side of the road. No injuries, but hurt fenders, bumpers, and quarter panels. So, the scenarios are endless.
I'll admit, back in my younger days when cell phones came out, I texted and drove all the time. I remember times looking down at a text, replying, and then looking up and wondering where the last half mile went. It's definitely dangerous and I am fortunate I didn't hurt myself or others. (ugh that makes me feel old. "back in my day sonny, when the technology of cell phones arrived"). They illegalized all cell phone usage in my area, even when sitting at a red light. I still see people on their phone constantly. People just suck, including younger me. The statistics are there, but unfortunately people get caught up in that mentality that "it won't happen to me"...….until it does.
