Tesla‘s latest Full Self-Driving software is demonstrating a substantial performance leap in early real-world testing, with version 14 achieving an average of 1,454 miles between critical disengagements.
The figure marks an improvement of over threefold when compared to v13.2, which averaged 443 miles between interventions.
City driving shows even more dramatic improvement, with v14 averaging 834 miles between critical interventions compared to just 217 miles for v13.2 — a nearly fourfold increase that suggests significant progress in navigating urban roads.
A critical disengagement is defined as a situation where human intervention was necessary to prevent an unsafe outcome.
“It’s still early, but ~25% of testers on the tracker with HW4 now have v14 & it will likely expand with it supposed to be going out to cybertruck soon,” wrote Elias Martinez, the owner of the tracking website, in an X post.
The tracker data, updated through November 1 at 5:39 PM GMT, encompasses 5,149 city miles and 2,173 highway miles across 579 recorded trips over a 25-day testing period from October 7 to November 1.
The progression across recent FSD versions demonstrates Tesla‘s rapid iteration on its end-to-end neural network approach.
For non-critical disengagements, where human intervention was preferred but not immediately necessary for safety, v14 shows 66.3% of drives with no intervention, with an average of 25 miles between any disengagement events.
Data Methodology and Limitations
The 1,677-mile figure displayed in the tracker’s main panel is based on sources that track detailed disengagement categories, Martinez explained in response to user questions about apparent discrepancies.
The chart on the left side of the tracker shows 1,454 miles because it excludes K3y devices, which don’t currently track disengagement categories but will in a future update.
“1.6k cuz that’s based sources that track categories for disengagements,” Martinez clarified in an X reply when asked about the difference between the 7,322 total miles shown and the 1,450 miles on the graph.
The tracker filters data to include only drives over two miles reported by at least 10 testers to ensure statistical reliability.
Martinez has also updated the tracker’s calculations to improve estimates for city versus highway mileage and disengagement events using speed data available in user submissions.
However, the results are based on a relatively modest sample size of 579 trips over 25 days.
The figure may shift significantly as more drivers log additional miles and encounter edge cases the system hasn’t previously navigated.
Geographic Variation in Performance
Geographic data shows notable variation across testing regions. British Columbia logged 214 entries across 2,332 miles with a 100% no-critical-disengagement rate, while North Carolina recorded 53 entries spanning 1,294 miles with 66% achieving zero critical interventions.
Ontario registered 56 entries over 733 miles with a 100% rate, as did California with 61 entries covering 564 miles and Illinois with 43 entries totaling 519 miles.
The variation likely reflects differences in road complexity, weather conditions, and local driving patterns and not geographic limitations of the software itself.
Rapid Release Cadence
The company began rolling out version 14.1.4 exactly one week ago, marking the fourth update in less than three weeks.
Tesla‘s rollout of version 14 began October 6, skipping v14.0 entirely and moving directly to v14.1.
Vice President of AI Software Ashok Elluswamy said at the time that multiple follow-up versions with “significant improvements” would arrive before year-end.
Cybertruck Deployment Imminent
Tesla‘s Cybertruck account weighed in on the timing of the v14 rollout in a Halloween-themed exchange on X.
When asked “one more day for Cybertruck?” by a user, Elluswamy responded on October 8: “Most likely by the end of this month.”
Elluswamy wrote on Saturday: “Sorry, pushing for early access cyber release over the weekend,” in a X post.
Cybertruck owners — who have been waiting for FSD v14 access — may receive the software imminently.
Musk’s Ambitious Claims
Last month, CEO Elon Musk said “widespread use” of the new system would be available by version 14.2, adding earlier this month that “by 14.3, your car will feel like it is sentient.”
Musk has called version 14 the “second biggest update ever” to the FSD system, trailing only FSD 12, which was released to employees in late 2023 and represented a shift to end-to-end neural networks.
New “Tesla Ride” Program
On Friday, Tesla introduced a program called “Tesla Ride” in the US designed to encourage people to experience FSD firsthand.
Under the initiative, Tesla advisors will meet potential customers at their location and take them for demonstration drives.
“We’ll come to you and take you where you want to go. Hop in the driver’s seat and a Tesla Advisor will join you as your co-pilot,” the company explained.
“They’ll walk you through all of the car’s latest features including comfort settings, games that kids can play on the touchscreens and Grok AI, your AI companion who can answer all your questions and tell you stories,” it added.
Regulatory Scrutiny on Drive Modes
Version 14.1.2 reintroduced two driving profiles—”MAD MAX” for more assertive driving and “SLOTH” for slower speeds—that had been removed in earlier iterations.
The US National Highway Traffic Safety Administration said last week it contacted Tesla after drivers reported on social media that the MAD MAX mode could cause vehicles to exceed speed limits, raising potential safety and legal concerns.
