Aftermarket Telemetry-Severance Kit That Disconnects Cellular Modems And Trackers In Modern Connected Cars Without Killing Other Functions
About 90% of new cars track speed, braking, location, and phone use every few seconds and sell that data; FTC settled with GM/OnStar in January 2026 and Oregon and Virginia are now banning sale of geolocation data. Built-in opt-outs are unreliable, and disabling connected services often kills crash detection or remote unlock. There's a clear gap for an installer-driven aftermarket kit (or paid service) that physically severs the cellular modem, blocks data plane traffic to manufacturer endpoints, but preserves Bluetooth, CarPlay, and local infotainment.
The hard part isn't snipping the antenna, it's keeping the dealer warranty intact and not disabling crash detection. The real product is a service network of trained installers that can warranty their work, not a Kickstarter dongle. That's why nobody has shipped it yet.

Legal opt-out routes are improving but slow and per-state. The market gap is a physical, installer-grade product that severs telemetry while preserving the user-facing features (CarPlay, hands-free, music, remote unlock via aftermarket replacement). No reputable installer chain currently markets this.
