Haven't you been arguing against practically everything that the majority of r.a.d regulars believe in? Things like keep right except to pbutt, 85th percentile speed limits, etc and so forth? I may be mistaken, but I think that was you, right?
In any case, that boredom, that feeling they can do other things while driving, from phone calls to eating lunch comes from the idiotcy of lowest common demonator driving in the USA. Low speed limits, no lane displine, etc and so forth. When I did my drive the speed-limit experiments to prove how out of touch the speed limits were I became so bored while driving, I wanted a TV to watch or a computer to use. That's what happens when driving is dumbed down.
People get bored. Some compensate in other ways, by driving faster and using traffic a series of problems to solve. Finding better ways around, etc and so forth.This is good, because it demands paying attention to the road and the conditions in fine detail. Some compensate in other ways that are negative. Such as by taking risks, cutting people off, pbutting on shoulders, and just generally being reckless. Others yet just decide to watch TV, read the paper and talk on the phone.
Since there is no lane displine, the system such that no matter what you do the other guy has to avoid you, there are no consquences to reading the paper or cutting people off. Thusly no consquences to driving distracted until actually hitting something.
