Autonomous driving in a modern car is not just about pressing a button. Activating advanced assistance functions depends on the manufacturer, the vehicle’s equipment level, and increasingly, the regulatory framework of the country where you are driving. In Europe, the situation differs significantly from that in the United States: software options visible in the dashboard menus may sometimes remain inaccessible due to a lack of local approval.
Approval and Activation: The European Regulatory Lock
Purchasing the advanced autonomous driving option does not guarantee that you can use it. This is a point that many drivers discover afterward. For example, on Teslas sold in Europe, the FSD system remains limited to assisted driving functions until approval by the competent authority (the Dutch RDW for the European market) is granted.

Belgium stands out as a recent exception: Teslas equipped with Full Self Driving are now allowed to drive on all roads in the country. The system includes lane keeping, automated lane changing, sign recognition, and stopping at red lights or stop signs. However, this Belgian authorization remains a national decision, and other European countries have not followed suit at the same level.
For French owners, the consequence is direct: even if the car’s menu displays advanced driving options, their actual activation depends on a regulatory green light that, to date, has not been given for supervised FSD.

Activating Autonomous Driving According to the Car Manufacturer
Activation procedures vary significantly from one brand to another. What is common is that most level 2 assisted driving systems (hands on the wheel, constant monitoring) are accessible from delivery on models that are equipped with them. The difficulty begins with higher levels.
Tesla: Between Software Purchase and Remote Update
On a Tesla, activation involves purchasing a software package (Enhanced Autopilot or FSD) via the app or online account. Once the payment is validated, an over-the-air update unlocks the features on the vehicle, sometimes within hours. The driver then accesses the settings from the touchscreen, in the Autopilot menu.
However, without European approval, the purchased FSD is limited to assisted Autopilot: adaptive cruise control, lane centering, emergency braking. Autonomous navigation functions on secondary roads or in the city remain locked on the software side.
European Manufacturers: Activation at Dealership or by Subscription
At Mercedes, the Drive Pilot system (approved level 3 in some countries) activates differently. The driver must drive on a compatible stretch of road (highway, speed limited), and the vehicle itself offers to take over via an indicator on the dashboard. Activation then occurs by pressing a physical button on the steering wheel.
Other manufacturers like BMW or Xpeng offer monthly subscriptions to unlock advanced functions. This means that activation can be temporary and linked to a recurring payment, not just a one-time purchase. On a Xpeng G6, for example, owners report having to manually configure the autopilot via the vehicle settings after subscribing.
Technical Checks Before Activating the Autonomous System
Before launching autonomous driving for the first time, several hardware conditions must be met. Ignoring these prerequisites can simply prevent the system from triggering, without a clear error message.
- The sensors (cameras, radars, possible LiDAR) must be clean and unobstructed. A dirty windshield or a sensor covered in mud is enough to disable the system.
- The onboard mapping must be up to date. Some level 3 systems only activate on road segments mapped in high definition.
- The vehicle’s software must be in its latest version. Manufacturers regularly deploy updates that fix bugs or expand operational areas.
- The driver must have accepted the terms of use of the system, often via the central screen or the manufacturer’s mobile app.
These checks may seem basic. However, they are the primary cause of frustration for drivers attempting to activate autonomous driving and failing to do so.

Safety and Driver Responsibility in Autonomous Mode
Activating autonomous driving does not transfer responsibility to the vehicle. In Europe, the driver remains legally responsible at all times at level 2, which concerns the vast majority of equipped modern cars. Hands must remain on the wheel, and eyes must be directed towards the road.
At level 3, the situation partially changes: the manufacturer assumes responsibility during the phases when the system is active and under the specified conditions (type of road, speed, weather). However, the driver must still be able to regain control within a few seconds when the vehicle requests it.
This distinction has a direct impact on car insurance. Some insurers are beginning to adapt their contracts to incorporate autonomous driving systems, but coverage varies according to the level of autonomy actually approved for the vehicle, not according to what the manufacturer announces in its marketing communication.
What Activation Changes in Daily Life
Once the system is activated and functional, the driving experience transforms mainly on highways and in traffic jams. The vehicle manages acceleration, braking, and lane keeping. On the most advanced models, it can also change lanes after the driver validates it via the turn signal.
Field feedback varies on the actual comfort of these systems. Some drivers report a notable reduction in fatigue on long trips. Others find the constant supervision (auditory alerts if hands leave the wheel) more stressful than manual driving.
Thus, activating autonomous driving in a modern car remains a multi-step process, conditioned by the vehicle’s equipment, local legislation, and regular software updates. The European regulatory framework is evolving, as shown by the Belgian authorization of FSD, but each country is progressing at its own pace. Checking the compatibility of your vehicle and the current approval conditions remains a prerequisite for any activation.
