Maybe this "ambien" drug is the reason for the latest Slothly driving.
I saw a driver in an SUV last week drift down an acceleration lane at a
very Slothly speed, holding up a bunch of cars behind it.  The other
drivers waited for me to pass, instead of swerving around the SUV.  But
the SUV driver, after running out of room on the acceleration lane and
ending up on the shoulder, tried to drift in front of me as I was
starting to pass.  I forced the SUV back onto the shoulder.  The SUV
driver then drifted into the gap behind me, as the other drivers swerved
around on the left.  Unlike the usual merge-impaired MFFYers, this SUV
driver didn't seem like it was aware that it was entering a
limited-access roadway.
