^^^^ Jake, I agree wholeheartedly with your perception of people CAN be trained to multitask. I like you am a Military brat. I grew up on a farm, so learning to multitask, was with me at a early age, driving a tractor, reading the instruments, while at the same time, changing the depths of tines.
That was simple, but when in the Army, to pass our license, with had to pass a advanced driving course, on a Skid pan. Then driving Armoured vehicles, while listening to the commander, and/or radioing in co-ordinates was he same.
Then it took me to driving Multi-Combination Trucks, mainly Road Trains, B-Doubles and B-Triples where there was 3-5 pivot points. I could drive these while on the UHF, and even reversing one around a corner, while talking to a operator, it isn't easy. (eevn reversing a B-Double requires thinking 2-3 steps ahead)
In all these situations, there are only certain people that can do this. When I became a Driving Instructor in the Military, I would fail 35-40% of participants, because they couldn't reverse even a single pivot trailer. No matter how hard we worked at training the individual, they just couldn't pick it up.
Its because of this, they would of been a danger on the road to other users, because it weeded them out, that they couldn't multitask like others could.
As I said above, I agree people CAN be trained, I have to say, that training people to multitask for the road, would be a bad idea. As it is now, there are instructors that will put people through the test and pass them, for one reason or another (we have all seen those drivers that you say "How on earth did they get a license"?? I do it every day more than once). So add to that, people being distracted while driving, and you would double the danger on the road.
I have never had a accident, in the 1,000,000's of Kilometres I have driven around the biggest Island on earth, and I know I could watch my NavMan, read text msgs, write text messages, and if possible, watch a TV show while I was driving, but there are people out there, that would crash, even if they were only listening to a Audio Book, because they would try to process the words being said, more than concentrating on the road. . . . Its too dangerous to let such legislation into the Law of the Road !!!
