I allow my family to use my cars, using landairsea gps I discovered my sister was driving over 90mph in a 70mph zone. I've also found they go to more places then they say. I like this gps because it allows me to put geo fencing around my home to let me know when my car leaves. It also updates really fast, which is great for real time tracking. My nephew will be driving my car soon when he gets his license, so I will be buying another gps for that as well.
