Its funny but most contracts wont tell you you have this kind of device on you. Its mostly for expensive cars that havent been paid in month. My brother worked as mechanic and people constantly came to remove it off the car. He used to do that for a fee because its not his responsibility to check who owns the car. He assumes whomever shows up at the shop with keys and money to pay for his work, hes ready to go.

I always wondered how much it pissed them off. One time out of curiosity they left device hooked to batter for some time. It took agent three weeks to show up (i bet you once you stop driving that where they send someone to try to pick it up). The agent was rude and angry to give out the car cause he seen device pinging from said location. Altho he didnt have warrant they let him in the lot out of shits and giggles just to waste his time in Georgia 103 degrees summer daylight to walk around the lot size of a football stadium in search for a grey Audi lol ;)
