Yep...There have been thousands of cases where a simple spilled drink, and or looking around for something in the vehicle turns into an utter fatal disaster. Throw in cell phones, a few curves in the road and it turns undivided highways into death zones. K walls save lives, but not all the time.
If I look away from my direction of travel, it’s for a slip second only. Gagging, coughing or health issues, one has to try to get off to the shoulder, and slow/stop as fast as possible, if possible.
Split second too!
A good TV show about accidents is “Collision”. It was on a few years ago. British.

I do not use my phone while driving. I pull over somewhere if i have to make a call.
