I tried a $99 plug that promises to track your car and send help when needed — without selling your data

Miles is a $99 plug-in device that tracks a car’s location, driving habits and vehicle health, and can provide accident response and roadside assistance. It is aimed partly at families with teenage drivers, offering parents and young drivers shared trip records and alerts in an attempt to support safety without hidden monitoring.

The device connects to a mobile app and includes an AI tool that explains dashboard warning lights and estimates repair costs. Miles costs $279 for the first year, including membership, or $396 for three years paid upfront; it works with most petrol and hybrid cars from 2008 onwards, plus some electric cars. The company says it does not sell vehicle or location data, encrypts data, and lets users stop location collection or delete their account; the reviewer found setup straightforward and the app easy to use.
