I can't drive and use a phone at the same time. I used to think I could but then I started paying attention and noticed that my speed was varying more. So I started using cruise control. But then I noticed that the truck was drifting more even after I had the steering checked and the wheels aligned. Finally, I remembered that when I used to do telephone technical support I was really good at it because I could visualize what was happening on the other end of the line so well that I wouldn't notice things happening at the next desk. The same thing was happening when I used the phone in the car -- I began to focus on the person I was talking to instead of driving. Yes, the bus was following too closely -- don't think that had anything to do with the driver's mind being occupied with something else?
I used to ride a motorcycle and I learned to drive it as if everyone else on the road was consciously trying to kill me. That's how I drive the car now -- with the phone safely ensconced in the backpack in the back seat. Often it's turned off because when I'm on the road it uses a whole lot of battery trying to find a signal when I'm in between towers. You want to use the phone, fine. Now if you don't have any kids, haven't bred, and want to cull your defective genes that's your choice. But I hope you're in your own lane separated from me by Jersey Barriers because I don't want your car pulling in front of my truck. I don't want your blood on my conscience.
