Never lose your car again. That sounds a bit funny. Let's rephrase it. Use real-time GPS to track the location of your car at all times. This device makes me think of some cool spy device used in numerous movies allowing you to track your enemy's vehicle after attaching some fancy magnetic GPS device on the inside of their rear wheel. Well it's not quite intended for that, but iTrack does allow you to sleep better at night knowing exactly where your car is at all times.
Just remember: If your car is stolen, and you have an iTrack installed, do not go to your car's location yourself. Hand the information over to the police. Tell them you have an iTrack GPS tracking device installed and you know your vehicle's location, this will make retrieving your vehicle and catching the criminals easy for the police.
