Sliders seem to target women far more frequently than men. This may be because a woman will often leave a purse or bag on the passenger seat when they get out of a given vehicle. The slider then only needs seconds to grab the item and escape.
After seeing criminals carrying out thefts in this manner, it was the police who were the first to call the offenders “sliders.” The term is based on the fact that the thieves are able to rapidly slide in and out of vehicles – often without even being noticed. Meanwhile, the fact that SUVs and other taller automobiles block the view more thoroughly while the driver is pumping makes them more of a target, as the thieves can then hide out of sight below the line of the windows.
