Mercedes' Answer to Tesla FSD Requires Hands on the Wheel
MB.Drive Assist Pro allows hands-free driving on highways but mandates hand-on-wheel supervision on surface streets.
Mercedes-Benz is preparing to roll out its MB.Drive Assist Pro system, a point-to-point automated driving feature that challenges Tesla’s Full Self-Driving (Supervised) approach by enforcing a hands-on-the-wheel requirement on surface streets.
What Happened
The MB.Drive Assist Pro system is set to be added to a large number of Mercedes’ electric and internal combustion vehicles early next year, with already-purchased eligible vehicles able to add it via an over-the-air update. Like Tesla’s FSD (Supervised), the Mercedes system allows drivers to enter a destination and have the car drive them there and park. However, while the system operates hands-free on controlled-access highways, it requires the driver to keep a hand on the wheel when navigating surface streets. Mercedes Chief Technology Officer Jörg Burzer described the system as a "Level 2 Plus Plus" feature, emphasizing that under this classification, the driver remains responsible for the vehicle, unlike a Level 3 system where the software assumes responsibility.
Why It Matters
The distinction highlights a philosophical split in the autonomous driving market between strict adherence to SAE autonomy levels and user experience preferences. Mercedes argues that surface streets are too chaotic for hands-free operation at Level 2, a stance that resonates with some drivers who prioritize immediate reaction time. However, Tesla FSD users accustomed to hands-off driving on all roads may view the requirement as a step backward. Antonio Hidalgo, a Tesla owner in Los Angeles, stated that while he might appreciate a Mercedes interior, he would not switch if it required keeping his hand on the wheel. Conversely, Mercedes contends its sensor suite—which includes five radar sensors and 12 ultrasonic sensors alongside cameras—provides superior safety data compared to Tesla’s camera-only approach, though the brand acknowledges that customers are unlikely to switch solely based on sensor specifications.
The Bottom Line
MB.Drive Assist Pro represents Mercedes’ attempt to offer point-to-point autonomy while maintaining strict driver supervision on complex urban roads, contrasting with Tesla’s more permissive hands-off approach. The system’s market success will depend on whether drivers prioritize the perceived safety of hands-on supervision or the convenience of hands-free operation in city environments.
