Tesla's Autopilot: A Glitch in the Matrix?
December 21, 2024
This past Friday, while driving south on Highway 101, my Tesla's Autopilot system encountered a "glitch" during a routine merge. Despite clear weather conditions – no fog, glare, rain, or snow – the system seemed unable to decide where to position the car within the lane, wavering back and forth indecisively. I had to quickly disengage Autopilot and take manual control to avoid a potential accident.
The "Unlearning" Dilemma
This isn't the first time this particular merge has tripped up my Tesla. I've reported it as a bug to Tesla numerous times, and while they previously addressed the issue, it appears to have resurfaced with a recent software update. It's as if the car has "unlearned" how to navigate this specific merge.
While I remain vigilant and always ready to intervene when Autopilot falters, this incident raises serious questions about the readiness of Teslas autonomous driving technology, especially considering Elon Musks ambitious claims about Full Self-Driving (FSD) being ready for widespread use by 2026.
If the system struggles with a relatively simple maneuver like a merge on a clear day, how can we trust it to handle more complex scenarios, especially those involving unexpected obstacles or adverse weather conditions?
The Camera-Only Bet
This incident highlights a critical concern with Teslas approach to autonomous driving: over-reliance on cameras without incorporating lidar or radar. While Tesla claims its camera-based system is sufficient, many experts believe that relying solely on cameras can create vulnerabilities, particularly in situations with reduced visibility or challenging road geometries.
Driver Complacency: The Human Factor
Furthermore, this experience underscores the potential for driver complacency. While I actively monitor Autopilot and readily take control when necessary, not all drivers may be as attentive. If a less vigilant driver were behind the wheel during this merge glitch, the outcome could have been far more dangerous.
The NHTSA is currently investigating Teslas Autopilot and FSD systems, examining their performance in challenging conditions and the potential for driver misuse . My recent experience provides a real-world example of the limitations of these systems and the need for continued scrutiny and improvement.
While Tesla continues to push the boundaries of autonomous driving technology, incidents like this serve as a stark reminder that we are still a long way from achieving truly self-driving cars. Until then, driver vigilance and a healthy dose of skepticism remain essential.
Where Do We Go from Here?
Tesla’s relentless innovation keeps pushing the boundaries of autonomous driving. But incidents like this one remind us how far we are from vehicles that can handle any situation with complete autonomy. I will continue to use AutoPilot because it is convenient and I consider it "glorified cruise control." But, would I allow the car to fully drive itself? Would I invest in Full Self-Driving? Would I get into a Tesla RoboTaxi? No. Definitely no. And, hell no. (Although, I would get into a Waymo. Their sixth generation system is a leap forward in autonomous technology featuring 13 cameras, 4 LiDARs, 6 radars and external audio receivers (EARs.))
For now:
Developers must double down on system reliability, testing for edge cases and regression issues.
Regulators need to ensure realistic expectations and safe deployments of these systems.
Drivers must stay vigilant, treating current systems as an assistive tool—not a chauffeur.
The Boasts of a CEO vs. Reality
As we speed toward a self-driving future, it’s worth remembering that technology’s most exciting advances are also its most humbling reminders of human fallibility. The road ahead may be paved with innovation, but until machines can navigate the complexities of merging traffic on their own, we’re all still in the driver’s seat.
While the CEO of Tesla may like to make some big claims of future capabilities, the reality behind the wheel is different. The cars still clearly require the human-in-the-loop for interventions and until the technology catches up to Waymo, the humans will need to stay in the seat for a long time to come.

Key Takeaways FAQ
Why did Tesla’s Autopilot struggle? Likely due to regression bugs in its software update, compounded by the challenges of vision-based AI.
Why does Tesla avoid lidar or radar? Tesla believes cameras are sufficient for autonomous driving, focusing on cost and scalability. Critics argue this sacrifices robustness.
What’s the risk of driver complacency? Over time, drivers relying on semi-autonomous systems may become less vigilant, posing safety risks.
How is the NHTSA involved? The NHTSA is investigating Tesla’s Autopilot and FSD programs for safety concerns and potential misuse.
Are we close to Full Self-Driving? No. While Tesla is making progress, incidents like this highlight the gap between current capabilities and true autonomy.
