Ticket for Driving in Google Glass

In California last week, a woman received a ticket for speeding and then an additional citation for wearing her Google Glass. And the debate still rages on over whether it was valid. The officer considered the head-mounted display a monitor that was visible to the driver. Traffic laws vary state by state, but many now have broad distracted-driving laws or bans on certain monitors that could easily apply to Google Glass. The turn-by-turn directions on Glass can be turned on with a voice command. The display will show a map view, but for extra safety the screen can be turned off while driving so there's only voice navigation. These laws create a very thin line that officers have to walk because on one hand, the device can be used as a navigation device but on the other hand, it have phone service capabilities built in.
