I suppose some of the variation between Boston drivers and the rest of the
country is due to the progressive Massachusetts Driver Education Manual which
I happen to have in my top desk drawer.  Some of the Tips for Better Driving
are worth considering, to wit:

[131.16d]:
       "Directional signals are generally not used except during vehicle
        inspection; however, a left-turn signal is appropriate when making
        a U-turn on a divided highway."

[96.7b]:
       "When paying tolls, remember that it is necessary to release the
        quarter a full 3 seconds before passing the basket if you are
        traveling more than 60 MPH."

[110.13]:
       "When traveling on a one-way street, stay to the right, so as not
        to interfere with oncoming traffic."
