Cross-Make 'Car Lobotomy' Service and Per-VIN Guide That Shows Exactly What Your Car Collects and How to Shut the Telemetry Off Without Killing Safety Features
Privacy-conscious car owners reacting to fresh reporting on how much modern vehicles record and sell are trading DIY hacks on HN (pull fuse 8, yank the cellular/TCU bridge, flip flags in ForScan, even desolder the chips) and one says outright that he would pay for a professional version. They want a plain-language, cross-make tool or service that tells them what their specific vehicle collects and exactly how to disable it, software-only where possible, without breaking OTA updates, eCall, or other safety systems.
The defensible product is the per-VIN knowledge base plus a vetted local-shop or mobile-mechanic network, not a magic universal off switch. Lead with 'here is what you keep and what you lose on YOUR model' because the trap is that newer cars bake the modem into safety-critical modules with no clean disconnect, and promising total silence will get someone's eCall or ABS killed.

Disabling car telemetry is possible but the how-to is splintered across brand forums and one-off diagnostic tools, with real risk of breaking safety or CAN-bus functions. Nothing gives a typical owner a safe, model-specific, step-by-step answer for their exact vehicle, and newer cars deliberately make the modem harder to isolate.
