For many commuters, the daily journey, especially through winding scenic routes like Laurel Canyon from the San Fernando Valley to Los Angeles’ west end, can be a test of endurance. Lucian Capellaro, a regular on this route, understands this well, navigating what he describes as a tedious, relentless ordeal.
Capellaro, like many, has listened intently to colleagues praising Tesla’s Full Self-Driving (FSD) feature, which promises effortless navigation to any destination. While the concept of automated driving sounded appealing, he remained unconvinced, primarily due to personal preferences regarding vehicle design, interior quality, and body style, beyond any political considerations.
However, Mercedes-Benz is poised to introduce an alternative that could appeal to drivers like Capellaro. Its MB.Drive Assist Pro point-to-point automated driving system is slated for integration into a significant number of the brand’s electric and internal combustion vehicles early next year. Existing eligible vehicles will also receive this advanced driver-assistance system via an over-the-air update.
Mercedes-Benz Introduces MB.Drive Assist Pro
The MB.Drive Assist Pro system functions similarly to Tesla’s Full Self-Driving (Supervised), allowing drivers to input a destination and have the vehicle navigate and park autonomously. Yet, a fundamental difference distinguishes the two advanced driver-assistance systems.
While both Mercedes and Tesla systems allow hands-free operation on controlled-access highways, the Mercedes-Benz MB.Drive Assist Pro requires drivers to maintain a hand on the steering wheel when operating on surface streets. This hands-on requirement is central to Mercedes’ design philosophy.
Philosophical Underpinnings of Mercedes’ Approach
Mercedes-Benz states that this design choice is not indicative of inferiority but rather reflects a strict adherence to the Society of Automotive Engineers (SAE) definitions for autonomous driving levels. MB.Drive Assist Pro, much like FSD (Supervised), is classified as a Level 2 system, which Mercedes refers to as “Level 2 Plus Plus,” necessitating constant driver supervision.
True Level 3 systems, by contrast, permit drivers to disengage from driving tasks, such as watching a movie or reading a book, under specific operational conditions. This distinction underscores a critical boundary in automotive autonomy.
Jörg Burzer, Mercedes Chief Technology Officer, explained this pivotal differentiation to InsideEVs: “There is a very important borderline between the levels. That borderline is that with Level 2 Plus Plus, you are responsible. At Level 3, the machine, the car, the software stack, is responsible.”
Burzer highlighted that while controlled-access highways present a more predictable environment for a Level 2 system, surface streets are inherently more dynamic and complex. Consequently, Mercedes-Benz mandates driver engagement on non-highway roads to ensure safety and maintain accountability.
Driver Perspectives on Hands-On Requirement
This decision resonates with some drivers, including Capellaro, who, despite being a motorcycle rider and not risk-averse, sees the logic in it. “Think about the reaction time it must be for someone to take their hands from off the wheel to on the wheel,” he said. “I’d view my hand on the wheel as lessening the seconds of reaction time to something crazy happening.”
Customer research conducted by Mercedes-Benz in Europe suggests a similar sentiment among drivers. Burzer noted, “In the city, they like to have something, some regulation or some requirement that you have to have a hand on the wheel,” though he added, “I don’t know about U.S. customers yet.”
When directly confronted with why a consumer would choose Mercedes’ system over Tesla’s, given Tesla’s hands-off capability on surface streets, Burzer reiterated the importance of regulatory compliance and adherence to SAE autonomy levels. He emphasized, “The big question is when is level 3 coming? Because then you can have the hands off (anywhere).”
Tesla FSD Users Express Skepticism
Many Tesla FSD users, however, believe their vehicles have already achieved a level of autonomy that transcends strict SAE definitions. They tend to evaluate the system based on its actual performance rather than theoretical classifications.
Antonio Hidalgo, another Los Angeles resident, frequently uses FSD and even admits to occasionally napping while driving, albeit while wearing a hat and sunglasses. He reports that the system’s flaws are now largely confined to parking functions.
When asked about the prospective Mercedes-Benz MB.Drive Assist Pro system, Hidalgo pondered, “If the (Mercedes system) worked the same but I had to keep my hand on the wheel …” He concluded, “You know, I probably wouldn’t (make the switch). I mean, I think I would be interested in having a nicer car with a better interior. But no.”
Mharlon Barrientos, who relies on FSD for his commute in Indianapolis, initially hovered his hand over the wheel but now operates his Model Y fully hands-off due to system updates and increased trust. He stated, “Having a hand on the wheel as a requirement would be a bit of a step back to the feel of full autonomous driving that I’ve gotten used.”
Mercedes’ Multi-Sensor Advantage for Advanced Driver-Assistance Systems
Mercedes-Benz asserts that MB.Drive Assist Pro holds distinct advantages over Tesla FSD (Supervised), particularly in its sensor suite. While Tesla primarily uses cameras to perceive its environment, Mercedes integrates five radar sensors and twelve ultrasonic sensors, alongside cameras, to feed raw data to its Nvidia-powered computing platform.
Christoph von Hugo, Mercedes’ Head of Active Safety, highlighted this comprehensive approach. “Different sensor inputs increases performance and safety,” he affirmed. In a subtle critique of alternative methodologies, he added that “Relying on one just is not enough.”
Von Hugo further indicated that Mercedes-Benz would only advance to Level 3 autonomous capability upon the addition of LiDAR technology, supplementing its existing camera, radar, and ultrasonic sensor array. (It is notable that Mercedes had previously offered a Level 3 system in the U.S. for a period, which has since been phased out.)
Despite Mercedes’ emphasis on its advanced sensor technology, Barrientos expressed skepticism about its impact on consumer appeal. “I honestly haven’t even thought about the tech behind it, so I’m not so sure knowing that there’s radar and ultra-sonic sensors (on the window sticker) would be a huge selling point,” he commented.
He suggested that tangible performance advantages, demonstrated through videos or reviews, would be more persuasive. “Just like the Tesla system, I think it would take me some mileage on both highway and streets to gain a trust for the system to know it’ll handle either situation well,” Barrientos added.
Consumer Priorities and Future Outlook
Barrientos also clarified that his loyalty is not solely tied to Tesla or its FSD feature, representing a broader segment of EV owners. He emphasized that the hands-on requirement, while a consideration, would not be the sole determinant in his car-buying decision if the overall vehicle package was appealing.
“The hands-on requirement in the city would not be enough to sway me off of the car provided I like the rest of the car,” Barrientos stated. “While I like the functionality of FSD, it’s still a bit further down the list of what I look for in a car. Functionality, comfort, value … I still like to feel the mechanics and have the feel of actually driving a car.”
Capellaro echoes this sentiment, pondering how MB.Drive Assist Pro would compare to his wife’s BMW i4, which features adaptive cruise control and hands-free highway driving assist at lower, traffic-jam speeds.
“I guess I’d just have to experience (MB.Drive Assist Pro) for myself, but if it can navigate all the craziness that is Laurel Canyon through Hollywood, and it is literally just my hand resting on the wheel, and that’s it, then sure,” he said. “The fact that it’s truly point-to-point, then yes, that sounds super appealing.”
The crucial question remains whether Mercedes-Benz MB.Drive Assist Pro can deliver performance on par with Tesla FSD, even with its mandated hands-on requirement. Early passenger-seat experiences in San Francisco in January showed promise. A comprehensive review is anticipated soon to provide further insights into its capabilities and how its unique approach affects the overall driving experience.
