Hi! I work for a large auto loan lender. I have NEVER heard of a practice limiting where you can drive your car. I would imagine it would be bad for business (e.g., here's a car, you can't use it that much, have fun!).
Personally, I would protest VERY loud if I found my company was doing this.
Also, I'm mostly certain we do have trackers on many of our cars, and I would imagine the data is transmitted securely so husbands can't use that signal.
