What can Grok actually do inside a Tesla Robotaxi now — and how do you protect your privacy in a shared driverless car?

Tesla has taken the beta label off Grok in its Model Y Robotaxi fleet: Grok Voice 3.0 is fully integrated, riders sign in once on the car screen, handle email, shopping, calendar and coffee orders by voice through connected apps, and the car logs them out automatically at trip end. Useful — if you treat a shared car like the shared computer it is.

The driverless car that picks you up now has a voice — and it just graduated. Short answer: Tesla has removed the beta label and fully integrated Grok into the Model Y Robotaxi fleet, running Grok Voice 3.0 on software 2026.38.5.6 with Grok 4.7. Whole Mars Catalog confirmed it live on October 25, following the original Grok Bot launch on October 11.

You sign in once on the car’s screen, then talk: Grok can work through your email, shopping carts, calendar and even coffee orders through connected apps — and when the trip ends, the car logs you out automatically, so the next rider sees none of it. Why it matters: a shared car is a shared computer. The automatic sign-out is the feature that makes a personal assistant acceptable in a vehicle strangers ride in all day, and Grok Voice 3.0’s reported 97 percent voice-command success rate is what makes talking to it practical instead of frustrating.

But a microphone in a public cabin changes what is safe to say out loud — your words are spoken in a space other people, and other riders’ trips, surround.1. Sign in only if you need to. A short hop across town does not need your email connected.

The less you link, the less there is to protect.2. Never say card numbers, passwords or door codes out loud. Voice in a shared car is a public channel — type sensitive things on your own phone instead, or skip them until you are out.3.

Check the screen before you step out. Confirm it shows you logged out. The car is supposed to do this automatically at trip end — verify it the way you would check a hotel door is locked.4.

Tidy up afterwards in the app. Disconnect any Connectors you do not need, so a future trip starts from a clean slate.Pro tip: Treat any shared-car assistant session the way you would a public library computer: directions, messages and a coffee order are fine — no banking, no password resets, nothing you would not say out loud in a lobby.Ad’s take: Talking to the taxi is genuinely handy, and the auto-logout shows Tesla thought about the stranger who rides after you. Meet it halfway: enjoy the voice, guard the secrets, and check that screen before the door closes.
