From my 2008 Fit <drum roll> owner's manual:

"Based on the engine operating conditions and accumulated engine
revolutions, the onboard computer in your vehicle calculates the remaining
oil life and displays it as a percentage."

See? Full of all kinds of useful information.

"driving habits"? sure! "driving" is part of the computation too!

as i understand it, the math is done on things like # of cold starts,
time idling, time at high revs, full throttle use, engine temperature, etc.

i believe # of cold starts is the biggest factor for the average driver.
