No, I don't drive in the desert. I also track all vehicles around me, all sides and make extensive use of my mirrors. I know that the lane beside me is clear for the lane change before I turn to look, but I still double check. Perhaps the difference is that this tracking does not require all of my attention. Different people have different mulbreastasking abilities, and to suggest that because a task requires all of your attention the same task must also require all of my attention is absurd.
No, apparently I don't since I'm apparently more capable of mulbreastasking.
Ever notice a musician (no I'm not a musician) playing separate parts with left and right hands, perhaps piano or drums? This is a learned skill, when you first start you have great difficulty mulbreastasking like that.
Ever notice one of those people that gives you the feeling that they are acutely aware of everything around them even though they are having a perfectly ordinary conversation? That because they are aware of everything, they have learned to be highly observant while mulbreastasking.
Again we're talking about text messaging on a cell phone which is a small keypad with a small number of buttons and can be operated single handed. The text pagers where the have a tiny "full" keyboard are an entirely different thing.
