When installed in a car, a vehicle tracking system can also identify and alert you to erratic driving. This might mean a thief is trying to escape the area where the car was stolen. It might also mean something is medically wrong with the person driving the vehicle. The devices that include a camera installed on the dash board can even allow you to identify the driver.
A vehicle tracking system can be used to spy on a spouse or a teenaged driver. But there are other very positive advantages to installing a fairly sophisticated system in your cars. For example, if you think your teenager is spending too much time in the wrong places, you can track and document their activities. Placed in the vehicle of an aging parent, you could be alerted to the kind of driving that would indicate a medical emergency (such as heart attack or stroke) or would help you know that a parent with minor memory or other cognitive problems is safe.
Some vehicle tracking system equipment is also able to track driving habits. It might, for example, track and record driving speed, cornering speed, tailgating, too rapid acceleration after a stop, failure to come to a complete stop, and more. This information could be used to help a new driver become a safer and more fuel-efficient driver.
