Can an app on a phone really do that? If it can, that's pretty scary. How would it know what car you were in, and if you were just riding in the car with a friend as opposed to driving yourself?
Oh for sure an app can do that...I do my best to restrict any apps from unnecessarily tracking my location. The Progressive app doesn't have location permission on my phone, but you never know.
The only apps I use that have background access to my location (ie, access to my location even when the app itself is not open/running) are Google Maps and the app for Kota's GPS collar.
But yeah, you have a good point. Progressive would basically have to subpoena my location information if I made some insurance claim and they disputed the circumstances since I'm not enrolled in their driver monitoring service. But yes, if I was enrolled in such a program, they can just do said monitoring right through the app I believe, as well as an OBD dongle.
A dash cam is a much easier option to protect yourself. Speaking of which, I still need to put my dashcam in the new Taco.
