OK, I started in the street near my house. Turned a 270 degree left turn
(around a ~30-ft circle) then 90 degrees right and went down the street to
a stop sign, left turn and on a couple hundred feet to a larger circle,
which I circled 1.25 times at a near-steady 20mph, then went on to the
convenience store.  The entire trip was about 4 minutes, about 1.5 miles.
Top speed was just over 30 mph (25mph limit throughout - don't send my GPS
log to the cops ;)  The Freerunner was sitting on the floor on the
passenger side of the car, about 10" right of centerline, with the Y axis
(top to bottom of screen in portrait mode) aligned to the direction of
travel.  So Positive-Y indicates vehicle deceleration, Positive-X indicates
left turn, Negative-Z means the car probably bounced upward.

Below is the output at roughly 1-second intervals from the accelerometer
(#1, not #0, so axes aligned to housing) followed by the trip log from
TangoGPS for the same time period.  Top speed was just over 30 mph (25mph
limit throughout - don't send my GPS log to the cops ;)  There is at most a
5-second difference between start and stop points of the two datasets, and
the right-hand turn off the small circle in front of my house should
provide a good sync point (accel data goes negative first time), as will
the ~30 second stop at a traffic light, ~20 seconds before data stops.
