The question when leaving a party, a bar, or a nightclub can be asked if you have had too much to drink and are therefore unfit to drive. Impaired driving is so often an issue and there are rarely instances that do not end in an accident, and a loss of life. These issues could be resolved by a new addition to the automotive GPS device. Two manufacturers have created a new addition in their GPS devices that can test for high blood alcohol levels. GPS manufacturer from Portuguese, Ndrive, now offers the G400, while Italian manufacturer, AvMap, brings you the Geosat 6 Drive Safe GPS device with a built in breathalyzer device. However, the implications that come with this new gadget are abound, and sometimes frightening.
