Has nothing to do with that. A vehicle can be a deadly weapon and should be operated with safety in mind.
Question: if you were shooting a weapon for accuracy at the range, while practicing the required safety, would you shoot your weapon while taking on a cell phone?
This is basically a yes or no question.
“This is basically a yes or no question.”
No, it isn’t. I can drive with one hand. Lots of amputees have to.
However, there are weapons I cannot fire very accurately with one hand. Matter of fact, for maximum accuracy I like to use two hands for all weapons.
Therefore, if you like, I’d be happy to recite Latin backwards through a hands-free cell phone while firing.
If you put up a man-sized target and count everything within the torso as max points, be glad to put rounds into it while holding a cell phone to my ear and discussing complex subjects.
Just get used to it: some people have enough wetware processor cycles to drive and talk at the same time.
