The Best Features Tesla Has Added Over The Years With Software Updates

For many years, buying a car meant accepting a fixed set of features for its lifetime. Tesla changed that expectation by treating the vehicle infotainment system like a smartphone, delivering major new capabilities through free over-the-air software updates.

The community is currently anticipating what some call the "final boss" of Tesla software: Unsupervised Full Self-Driving. While a global rollout has not happened yet, there are early signs of that future — recently, Tesla launched completely unmanned Robotaxi rides in Austin, where vehicles began picking up passengers without a driver or safety monitor inside.

Before full autonomy arrives everywhere, here are the most notable features Tesla has added to owners' cars over the years.

Full Self-Driving (Supervised)

The centerpiece of Tesla's software lineup is its driver-assistance suite, commonly known as Full Self-Driving (Supervised). Built incrementally through years of fleet data, the FSD system in beta can navigate city streets, handle traffic, yield to pedestrians, and automatically park the vehicle at the trip destination.

Navigate on Autopilot

An early step toward FSD, Navigate on Autopilot lets the car drive from an on-ramp to an off-ramp, including automatic lane changes and handling highway interchanges. It turned long-distance driving into a more relaxed experience.

To encourage FSD adoption and phase out the older Autopilot option, Tesla recently removed Autopilot from new vehicles, leaving Traffic Aware Cruise Control (TACC) as the standard cruise capability on new cars.

AutoPark

AutoPark was released via a software update in 2019 and has since been overhauled to be quicker and more precise. For vehicles with FSD, the system can actively search for a parking space and park the car autonomously.

Boombox / Custom Lock Sounds

In 2023, Tesla added the ability to replace the standard "honk" that plays when locking the car with custom sounds. Owners can pick from pre-loaded options — for example, the Light Cycle from the Tron franchise — by navigating to Toybox > Boombox > Lock Sound, or they can upload their own sounds using a USB drive. Other Boombox features let the car change its horn sound when parked and play audio through the external speaker.

Tesla Theater

When parked, the center screen can run streaming apps so the vehicle becomes a lounge. Introduced in 2019, Tesla Theater added apps such as Netflix, YouTube, and Disney+ for in-car viewing while charging. With certain workarounds, it's also also possible to view other web streaming services on the rear screen.

Video Games

Tesla Arcade began as TeslAtari with classics like Centipede and has grown into a modern in-car gaming platform. A recent noteworthy addition is the ISS Docking Simulator, which uses controls modeled on real NASA interfaces. Some games let drivers use the steering wheel as a controller, and titles like Beach Buggy Racing include leaderboards that can be viewed at Superchargers.

High Fidelity Park Assist

Complementing AutoPark, High-Fidelity Park Assist renders a 3D view of the area around the car on the screen. This visualization shows what the vehicle perceives and warns when the car gets close to surrounding objects, whether in front or to the side. Unlike FSD visualizations, this feature generates its own 3D models to represent nearby elements accurately.

Car Wash Mode

Car Wash Mode makes going through an automated car wash simpler by disabling certain systems — for example, it suspends auto wipers — and by making it easier to place the vehicle in neutral. It also disables parking chimes and the HVAC system and will alert the user if any windows, doors, or the trunk are left open.

Emergency Braking and Collision Avoidance

Tesla has pushed safety enhancements by software before some regulators required them. The company's Automatic Emergency Braking received updates to react to perpendicular dangers, such as a vehicle crossing an intersection, and to function when the car is traveling in reverse and at speeds over 100 mph. These improvements were rolled out broadly across the fleet, increasing safety for older cars as well.

Lane Departure Avoidance

Emergency Lane Departure Avoidance originally issued warnings when a vehicle drifted from its lane. An update added corrective steering so the car can steer itself back into the lane. The system detects drift without a turn signal and, if the vehicle is traveling over 40 mph, will automatically return the car to its lane to help prevent accidents caused by distraction or fatigue.

Additional Music Services Expansion

Tesla expanded its Music Services well beyond the original LiveOne option. Over time, the infotainment system gained support for services including Spotify, SiriusXM, Apple Music, Amazon Music, and YouTube Music, among others.

Apple Podcasts Integration

In 2023, Tesla added native Apple Podcasts support to the infotainment system, enabling synced playback and progress between a phone and the car.

Grok Voice Assistant

Tesla integrated xAI's Grok chatbot into the operating system and, after subsequent updates, Grok can set and edit navigation destinations and serve as a conversational guide. Drivers can use natural language to locate types of stops along a route or navigate to saved favorites.

Dashcam and Sentry Mode

Sentry Mode uses the car's external cameras to monitor the surroundings when parked. Dashcam records footage while driving and now includes telemetry data such as speed and steering angle. Over time, the system has received UI updates, mobile app support, layout improvements, and expanded camera recording capabilities.

Tesla Light Show

The Tesla Light Show synchronizes exterior lights and mirror movement to music. Tesla periodically adds new songs via software updates and also provides tools for owners to create custom light shows.

Auto High Beams

Auto High Beams automatically switch between high and low beams based on detected light and nearby traffic, removing the need for the driver to toggle high beams manually.

Adaptive Headlights

Adaptive Headlights extend high-beam illumination by selectively dimming portions of the beam near other vehicles. Using an array of light pixels, the system can turn off individual pixels around oncoming traffic to reduce glare while keeping the rest of the road brightly lit.

Auto Wipers

Tesla has enhanced windshield wiper behavior via software, refining detection with neural networks so the system can better sense rain without an additional sensor, even though the feature is not considered the best in the industry.

Dog Mode, Camp Mode, and Keep Climate

These climate features maintain cabin temperature when the car is parked. "Dog Mode" displays an on-screen message indicating the cabin is climate-controlled for pets, "Camp Mode" keeps the vehicle powered for overnight stays, and "Keep Climate" maintains temperature during short errands.

Parental Controls

Parental Controls let guardians set a maximum speed limit, reduce acceleration, and prevent safety-critical features from being disabled, helping keep younger drivers safer.

Valet Mode

Valet Mode limits performance, locks the glove box, and protects personal data. While Valet Mode is active, home, work, and recent addresses are not visible; HomeLink and calendar access are disabled; FSD is turned off; and other privacy measures are enforced.

PIN to Drive / PIN to Open Glovebox

"PIN to Drive" requires a four-digit code before the vehicle can be shifted out of park, adding security even if someone has access to a phone or key card. Tesla also added the option to lock the glove box with a PIN. The on-screen keypad layout can change to prevent guessing a PIN from smudge patterns on the screen.

Weather, Radar Overlay, and Air Quality Index

A 2024 update added Weather and Air Quality information directly to the status bar so current local conditions and air quality warnings are visible. Tesla also introduced a weather radar overlay so drivers can follow storms while traveling.

Keeps Getting Better

Owners who bought their cars several years ago have likely seen many of these features arrive via software updates. As the fleet progresses toward broader autonomy, over-the-air updates continue to change expectations about vehicle capabilities.
