The NYPD has sent a letter to Google demanding that it remove a feature that allows users to post drunk-driving checkpoints on its Wave navigation app. In the letter, the NYPD argues that the feature is irresponsible because it allows impaired and intoxicated drivers to avoid checkpoints and therefore encourages reckless driving. Those users who post such checkpoints on the Waze app, the NYPD says, may be engaging in criminal conduct since such actions hinder the NYPD from enforcing DWI laws and other criminal and traffic laws.
