So my mother is starting to get up there, and is recently widowed, meaning that she drives herself when needing to shop, doctor visits. I want to keep a better eye on her when she is on the road, and am considering installing a GPS tracker on her car. I don't know if she would be cool with that, so I'm toying with installing it without her knowledge. The tracker module just plugs into the OBD-II port, so it's a very quick install. Sooo...if I put it on her car without her knowledge, am I being a caring son, or just a sneaky sack of s**t?
