Ha, go to New York..  You wouldn't believe how many stop
lights I sailed through before I noticed those little posts
on the right with the signals on them.  I haven't seen those
in ANY of the cities in NC, SC, or Virginia that I normally
drive in.  Was so tuned in to looking for lights overhead
that I completely didn't see the signals not being where
they were expected..

  Want to try something fun?  When the road's empty and you
have lots of room, lay your head over sideways and try to
drive.  Be expecting to go outside your lane if you have any
curves.  You'll get a real good feel for just how locked in
your brain's visual system is to the normal
horizontal/vertical attitude.
