A survey has found that men are more likely than women to ignore the directions given by their GPS navigation system, Reuters reports: 83 percent of men versus “less than three quarters” of women. (How much less?) Gender issues aside — perhaps the difference is overstated? — that’s a lot in either case. People are clearly (and properly) skeptical of their satnavs (otherwise, we’d be seeing a lot more stories about people driving off cliffs), probably because of bitter experience: according to the survey, one-third of respondents had their satnav lead them one to five miles off course, and nearly two-thirds kept a map in the car as a backup.
