Yes, the last part of what you say is so true. Too many things to distract drivers today, and text messaging being the post problematic where I live, second to drunks. There should be an automatic GPS tracking system that shuts the phone off when someone is text messaging while the phone is in motion. My sister-in-law drives for a living, and if she is caught using her cell phone (hand held) for any reason other than hands free through the companies blue tooth communication system, she will be instantly dismissed.
I just found out that the city I live in has the distinction of being the 3rd worst cities in the US for road fatalities, behind LA and NY (I believe them to be the two worst). In 2016, there were 115 fatal accidents on our roads, and 50 of those were because of drunks. On our major roadways within the city limits, the speed limit is 45mph (72kph), and most push 50 to 55. Ridiculous, and add that to the fact that many drivers here drive huge pick-up trucks and SUVs. Two months ago my wife was sitting at a traffic light. A huge pickup truck went barreling through the red light going from left to right in front of her just shortly after the light turned green for her. He demolished a small car killing the driver while he was making a legal turn. I'm glad that my wife has the good sense to delay moving off when the light turns green just to make sure traffic going across her path has stopped. It annoys drivers behind her, but too bad for them, poor diddums. She still has nightmares because of that accident. For the next week, I drove her back and forth to work, and even while doing that she was a nervous wreck. "Watch out for that car, etc.," she would keep saying. I wish I had a small Star Trek transporting devise in my car, if the technology was available. By the time I'm done during the day of driving, I would have caused a major traffic jam in Antarctica, because that's where I would have transported the bozos I would have encountered on the roads.
So when it comes to riding my bike, I stick to less traveled roadways that have bike lanes, and also bike trails, which fortunately we have plenty of both.
Stay safe out there.
