I have noticed recently that the TSA has created split lines at many airport security screening posts - one for experienced travelers and one for "casual" travelers - i.e. noobs.
I have no problem with the basic idea. Long ago I began advocating special lines for public electronic devices (airport boarding pass machines, supermarket self-checkout, ATM's) for people with IQ's over 90 because I always seemed to get behind the person who had never even seen a keyboard in their life.
But the actual execution of this concept in airports is laughable. In the last 4 airports I have been in, the split between passengers who know what they are doing and those who don't is only through the screener who checks ID. Even the lamest travel noobs are generally able to cough up an ID and boarding pass without too much trouble (though I will say I always seem to get behind the guy traveling on some bizarre 1930's-era League of Nations passport that seems to take forever to process). However, after this ID screening the two lines come back together and everyone is mixed again. Just in time to hit the x-ray screening station, where inexperienced travelers can hold up the line for hours.
