Such profiles can involve
things like driving within a city, on a highway, across some special uphill or downhill
terrain, to name but a few. Drive cycles only provide time, and corresponding speed fluctuations,
and labels attached to these tell us what kind of drive cycle it is, for example,
city, highway, and so on. Drive cycle data by itself does not reveal the terrain; it is the
label attached to the data which tells what the drive cycle has undergone.
