Report: Tesla FSD Works Well Most of the Time - Until It Doesn't

Tesla’s Full Self-Driving system (FSD) is impressive, but it’s not actually capable of driving a vehicle by itself. Rated at Level 2 on the SAE automation scale, FSD requires an attentive driver ready to take control at any time. Even so, independent research firm AMCI Testing’s recent study showed that the system functions almost flawlessly in most scenarios, boosting drivers’ confidence, but that sense of security can cause significant problems when things do go awry.


AMCI tested a 2024 Tesla Model 3 Performance running the newest hardware and software over 1,000 miles of city streets, interstates, mountain roads, and rural two-lane roads. FSD performed well, but the organization’s drivers had to intervene more than 75 times while using the system. That’s an average of one intervention every 13 miles, and some of FSD’s missteps sound pretty dangerous.


One tester reported that the vehicle crossed the double yellow lines on a twisty mountain road, while another said the Model 3 stopped at a green light during city testing. AMCI’s director of testing, Guy Mangiamele, said, “What’s most disconcerting and unpredictable is that you may watch FSD successfully navigate a specific scenario many times – often on the same stretch of road or intersection – only to have it inexplicably fail the next time.

That relatively low rate of driver interventions may build a false sense of trust and confidence that FSD is capable of self-correcting in confusing situations, leading to more crashes. The CEO of AMCI’s parent company, David Stokols, noted that “with all hands-free augmented driving systems, and even more so with driverless autonomous vehicles, there is a compact of trust between the technology and the public. Getting close to foolproof, yet falling short, creates an insidious and unsafe complacency issue as proven in the test results.”

    I rented a Model S equipped with "FSD" in April 2024. Despite being in the easiest possible scenario - wide, well-marked Texas state highways - it was terrifying. It had a hard time staying in lane any time the lane markings weren't absolutely perfect, it followed way too close, and it was reluctant to buy sharper curves (a couple of times forcing me to add steering input). It's not even the best Level 2 system I've experienced (that title would go to GM Super Cruise), let alone anything remotely close to "self-driving." I really liked that Model S otherwise but wish I had never even tried "FSD."

    Full self driving, or Autopilot, should be banned as well as any other system like it (Fords Blues Clues and whatever GMs system is called).

  • Redapple2 Resident HK hater here. Man they make good looking stuff. Compare a random HK to the -gm- style leader; the Lyricmedusa. HK has cohesive style - each model different yet handsome, compared with a jarring jumble of shocking discordant triangles, slashes and rhombi.
  • SCE to AUX "No one should be purchasing a new EV unless they have absurd levels of disposable income" Nonsense FUD, when many EVs cost less than the ATP of all vehicles. Is $40k an 'absurd level of disposable income'?
  • Jkross22 "Considering customers could purchase the now-discontinued (and comparatively ancient) Dodge Caravan for under $30,000 just five years ago, Voyager pricing feels a little high for what you’re getting. " $41,690 is a lot for an old product. An old Dodge product. An old minivan.
