Tesla is moving toward deeper voice control in its cars, and the next big step is likely voice‑driven control of Full Self‑Driving (Supervised), backed by Grok. Elon Musk also confirmed “Coming” to a suggestion that drivers should be able to speak naturally to FSD (Supervised).
This upgrade could matter most at the end of a trip, when the car has to decide exactly where and how to park.
Grok, the conversational AI developed by xAI, started to arrive in Tesla vehicles in mid‑2025 through an over‑the‑air software update in North America. It later expanded to more regions, including Europe, with early 2026 releases.
Right now, Grok acts mainly as a smarter assistant for navigation and general questions. Drivers can press the steering wheel voice button or tap the on‑screen icon and then speak naturally to set a destination, adjust routes, or find nearby services. This already reduces screen interaction, and it makes long trips more convenient. Yet Grok does not directly control hardware functions like windows or cabin temperature, and it does not replace FSD’s core decision‑making logic.
Path toward voice‑controlled FSD
Even so, Tesla is clearly preparing for a future where voice plays a bigger role in vehicle control. Code references and product briefings point to Grok as part of a broader “car assist” layer that is expected to handle more than simple commands over time. This stands in contrast to Tesla’s older voice system, which relies on rigid phrases and limited command sets, and often frustrates drivers when they do not say the exact wording.
Ashok Elluswamy (VP of AI at Tesla) has recently acknowledged that full voice control over the car is on the roadmap, but that safety testing comes first. “In the future, we will have fully integrated voice control commands that can control the vehicle. It’s just a bit too early for that. It opens up an entire area of testing that we have to do — for example, you shouldn’t be able to tell the car to crash, and it shouldn’t crash”.
As of today, Tesla keeps Grok and the traditional “Hey Tesla” feature somewhat separate. Yet many analysts expect these systems to merge, with Grok eventually handling both conversation and direct vehicle actions under strict safety guardrails.
Parking at the destination is one of the most obvious places where voice‑controlled FSD can help. Tesla’s recent FSD versions already offer “Arrival Options,” letting the driver choose how the car should behave once it reaches the address. The system can target a parking lot, street parking, a driveway, a parking garage, or a curbside drop‑off. The car can then remember these choices for saved destinations, which already trims friction on repeat trips.
Some FSD users say the system now handles almost all of their driving, with the main remaining friction around navigation tweaks and parking preferences at the end of the route. That is where a natural voice layer could fit neatly. Instead of tapping the screen while the car approaches a busy area, a driver could simply say, “Park in the garage when we get there,” or “Look for street parking near the entrance.”
This push does not sit in isolation. Tesla is preparing its Cybercab concept, a vehicle without a steering wheel or pedals, pitched as a fully driverless robotaxi. In that setup, spoken interaction will be central. Passengers will need a clear way to tell the car where to go and how to handle pickup and drop‑off, and a Grok‑style assistant is a natural fit.
As Grok gains deeper hooks into vehicle systems, the same technology should flow back into privately owned cars. Owners may first see it in areas like parking, arrival behavior, and low‑speed maneuvers, where the risk profile is somewhat lower but the convenience impact is high. Over time, voice control of FSD (Supervised) could shift from a nice‑to‑have feature into a standard way drivers guide their Teslas through the last moments of a trip.
