Despite there being very few Google Explorers out there with Google Glass, police have already managed to start fining. Google Explorer Cecilia Adabie was fined for wearing Google Glass while driving in San Diego, California.

The police officer pulled her over for speeding but then issued a further fine for wearing Google Glass. The citation was for violating Code Section 27602, which states: "A person shall not drive a motor vehicle if a television receiver, a video monitor, or a television or video screen, or any other similar means of visually displaying a television broadcast or video signal that produces entertainment or business applications, is operating and is located in the motor vehicle at a point forward of the back of the driver's seat, or is operating and the monitor, screen, or display is visible to the driver while driving the motor vehicle."

This is aimed at in-car entertainment but in this case has been used for something a little different.

Abadie's posted on Google+ that Glass wasn't functioning when she was driving, but that didn't seem to be the issue. "The arresting officer said it was blocking my view," she pointed out. Laws banning Glass while driving have cropped up in a few US states and is being considered by the UK's Department of Transport.

Despite these issues, Mercedes Benz is already working on integrating Glass into its cars. And INRIX has already developed an impressive satnav system for Glass. This is an interesting time for Glass - here's hoping we do get to use it for satnav, one of its most helpful talents.
