Maybe there should be a test for this. Driving while talking on the radio/cell phone/operating MP3 player/dealing with kids in the back/etc.
I'd expect that there would be a spectrum of ability. Younger folks who grew up with cell phones and multitasking probably do it better than OFs.
Also depends on where you drive. I drive long, barren stretches of straight road to and from work. Other people deal with traffic, traffic lights, pedestrians, etc. Sometimes there's weather to deal with.
Anyway, there doesn't need to be a law. People just need to be honest arbiters of their own capabilities, be responsible, and think safety first. Isn't that simple? Seems to work for the thousands and thousands of Americans who legally carry concealed weapons.
There are times when I am perfectly comfortable operating a mobile rig and times when I wouldn't be.
