In politics as usual the term:backpedal is used to describe a change of direction that does not meet the constraints set by the observer's ideology.

The point of view of this term as used in politics itself is entirely up to the faction making the accusation and assuming the direction, with this vehicle metaphor.

For instance, to cut corporate tax of any kind for any reason or permit private health care facilities at all, is to backpedal from the perspective of the NDP. But not even European social democrats agree with that view.

operational use

A software engineer uses "backpedal" in a much more objective and operational way to describe failure to meet constraints that are recognized universally in that profession. For instance, web design issues such as expressed in URL and 404 problem, that do not have any strong (or even known) counter-position.
