Tesla FSD v14 Just Drove 2,187 Miles With 1 Disengagement: Full Data Breakdown | Taha Abbasi

2,187 Miles, 1 Disengagement: Inside the Data

Taha Abbasi just completed what may be the most thoroughly documented autonomous cross-country drive in Tesla FSD history. His Cybertruck covered 2,187 miles from South Jordan, Utah to Newark, Delaware on FSD v14.2.2.3 — with a single disengagement so brief the odometer didn’t register it. Here’s what the data tells us about where Tesla’s Full Self-Driving actually stands in February 2026.

The Raw Numbers

Let’s start with Taha Abbasi’s own breakdown, posted to X shortly after arriving at his destination:

That’s a 99.995% autonomous driving rate. Out of 2,187 miles, only 0.1 miles were driven manually — the dirt path into the cemetery at the destination. The single disengagement at a toll booth in Montpelier, Ohio (mile 1,610) was a comfort brake by co-driver Nichell, not a system failure.

FSD v14.2.2.3: What This Version Handles

This trip was run entirely on Tesla FSD v14.2.2.3, part of the 8th deployment batch of version 14. The route threw nearly every challenge at the system:

• Mountain passes: The Rocky Mountains through Utah and Wyoming, including elevation changes, tight curves, and variable speed zones
• High crosswinds: Wyoming is notorious for wind gusts that push vehicles laterally — FSD maintained lane position throughout
• Plains monotony: Hundreds of miles of Nebraska and Iowa highways where the challenge shifts to construction zones and rural intersections
• Urban traffic: Illinois metro areas with dense merging and aggressive drivers
• Toll infrastructure: Ohio’s toll plazas — the one scenario that produced the sole disengagement
• Appalachian terrain: Pennsylvania’s mountain passes with steep grades and truck traffic
• Night driving: Much of the trip was driven overnight, testing FSD’s camera-only vision system in low-light conditions

For context, earlier FSD versions struggled with many of these scenarios. Version 14’s end-to-end neural network approach has shown dramatic improvements in handling edge cases that tripped up versions 12 and earlier.

Supercharger Economics: $0.00 Across 2,187 Miles

One of the most striking data points from Taha Abbasi’s trip: the entire 2,187-mile journey cost $0.00 in charging. The Cybertruck came with free Supercharging through September 2026, meaning all 16 Supercharger stops across nine states were fully covered.

To put this in perspective, a comparable gas-powered truck getting 20 MPG would have burned approximately 109 gallons of fuel. At a national average of roughly $3.20 per gallon in February 2026, that’s about $350 in fuel costs. The Cybertruck did it for zero.

The 16 Supercharger stops also served as the natural swap points for the relay system Taha and Nichell used — one supervised while the other rested, switching at each charging stop. The Supercharger network effectively doubled as their rest-stop infrastructure.

How This Compares to Other Autonomous Cross-Country Drives

This was the 4th vehicle to complete a fully autonomous cross-country drive on Tesla FSD, and the first Cybertruck. Here’s how the runs stack up:

Notable differences: Alex Roy’s drive was completed in the dead of winter. Taha’s was unplanned — an emergency run for a family funeral, not an optimized record attempt. The single disengagement was a human choice, not a system limitation.

The AI Co-Pilot Factor

What sets this trip apart technically isn’t just FSD performance — it’s the integration of AI systems beyond the vehicle itself. Taha’s AI assistant, Benny J Walker, built a real-time trip tracker during the drive, logging every Supercharger stop, state crossing, and FSD data point to a live dashboard.

This kind of real-time documentation — AI monitoring AI — represents an emerging pattern in how technology enthusiasts are validating autonomous driving claims with verifiable data rather than anecdotal reports.

What the Data Actually Proves

Let’s be precise about what this trip demonstrates and what it doesn’t:

It proves:

• FSD v14.2.2.3 can handle a 2,187-mile multi-terrain, multi-state drive with essentially zero interventions
• The Supercharger network supports cross-country Cybertruck travel with zero planning anxiety
• Supervised FSD enables long-distance driving that would be dangerous or impossible for a solo driver
• The Cybertruck platform handles FSD as capably as Model 3/S/Y on extended highway drives

It doesn’t prove:

• FSD is ready for unsupervised operation (this was supervised the entire time)
• Every FSD user will have the same experience (software versions, routes, and conditions vary)
• Toll booths are solved (still the one consistent edge case)

Taha Abbasi has announced a follow-up: a zero-disengagement coast-to-coast attempt. A full video documenting this trip will be published on his YouTube channel, The Brown Cowboy, within the next week.
