Rule of thumb

An approximate way of doing something based on presumptions rather than fact. Contrary to popular belief, the idea the law once allowed a husband to beat his wife as long as the device was no thicker than his thumb is false, as such assaults were outlawed for centuries in common law, although the ban wasn't generally codified in written law until the 1980s.

A driver kept going 5 mph over the speed limit, thinking the police had a rule of thumb that it was a waste of time to give out a ticket to anyone going anything lower than that.
