Tesla-Egress Guard

Reasons to doubt this
Editorial fact-check (sourced)
Editorial note: two premises do not hold. Tesla's own owner's manual states that cabin camera images and video do not leave the vehicle unless data sharing is enabled, and then only short clips after a safety-critical event, so 'continuously streams cabin camera' is wrong. And the card's form is already blocked: the Tesla app pins certificates and fleet telemetry uses mutual TLS, so a transparent LAN proxy cannot decrypt this traffic today. The card treats pinning as a future risk; it is present tense.

The pitch
Gemini
A self-hosted local proxy and firewall daemon that intercepts, visualizes, and blocks non-essential telemetry and tracking data sent from Tesla vehicles and home integration gateways before it reaches Tesla's servers.
Who it's for
Tesla owners and homelab enthusiasts who currently use standard routers or raw DNS-blocking software to control their IoT appliances.
The problem
Legal and privacy risks: Tesla vehicles continuously stream precise GPS coordinates, internal cabin camera streams, and driving behavior metrics, which are then sold or shared with insurance providers and data brokers.
How to build it
A lightweight Linux daemon (Go/Rust binary) with a local web dashboard that functions as a DNS server and transparent SSL-inspecting reverse-proxy on a home LAN.
How it makes money
SaaS builders and privacy-focused power users pay a one-time license fee of $49 for lifetime firmware/filter updates, as free alternatives like Pi-Hole only block at the DNS domain level and break official app connectivity entirely by blocking whole subdomains.
Why it doesn't exist yet
Incumbents like cloud security providers skip this because it requires custom TLS decryption profiles tailored specifically to Tesla's proprietary vehicle-to-cloud API endpoints. An indie builder can target the local network level directly, producing targeted decryption helpers and customized JSON filters.
First users
Early privacy advocates and homelab users on forums like Hacker News and r/selfhosted who want to halt high-frequency vehicle telemetry without bricking official mobile app controls.
Build size
2 people x 10 weeks: Includes a customized MITM proxy core for Tesla APIs, a local React dashboard, and a collection of curated blocking rules. Excludes hardware devices.
Biggest risk
Tesla could ship a mandatory vehicle firmware update enforcing hardcoded public key pinning (HPKP) on all API endpoints, completely bypassing the local MITM decryption bridge.
Conditions for a hit (all 3 required)
- Real-time visual stream displaying every outbound telemetry request payload with its volume, destination country, and coordinate frequency.
- A togglable configuration matrix allowing users to selectively block raw cabin video uploads and location breadcrumbs while keeping lock/unlock remote commands fully functional.
- A downloadable CSV file containing a weekly cryptographic audit receipt of blocked outbound data events, ready for legal and insurance disputes.
How it's judged (in 6 months)

AI self-confidence 65/100 — self-reported likelihood of meeting the criterion, not a business success rate
Exclusions ▾
- Generic router-level DNS ad-blockers like Pi-Hole or AdGuard Home that do not inspect and rewrite TLS payloads.
