FSD 14.3.7 crossed Puerto Rico in a downpour.
I intervened once.
One hundred three real-time miles from Luquillo to Aguadilla, with no cuts around the uncomfortable moments. This is what it did well, what it did strangely, and the one thing that made me take the wheel.
Watch the complete trip.
The video shows the FSD v14.3.7 road test, including the good moments, the uncomfortable ones, and the single intervention.
The numbers, untouched.
One intervention, but not for dangerous driving.
Across 103 miles of Puerto Rican roads — highway, traffic, tunnel, downpour, and residential streets — I took the wheel once, and not because of anything dangerous: the car stopped too far from the ticket machine.
What it did well and what went wrong.
What it did on its own
- Parked itself twice. At the charger it drove the aisles, chose a stall, and backed in between two cars. It also did it at the taquería. 1:58 5:19
- Waited before merging. In the rain, with a car in the blind spot, it opened the repeater camera, waited, and then changed lanes. 4:17
- Handled speed bumps without help. On the residential street at the end, it slowed and accelerated again on its own. 6:03
- Cyclists on the right. It let three cyclists pass on the shoulder without crowding them or leaving its lane. 1:07
What went wrong
- Stopped too far from the ticket machine. I took the wheel, repositioned it, and the streak reset. 0:17
- Three critical flags in the evaluation. CPX-03, HES-02, and OBS-03 cap the raw 8.5 score at 5.0.
The car celebrated it with confetti. 5:02
Halfway through the return trip, the car reached one hundred consecutive miles with FSD engaged and displayed a “100 mi” badge with falling confetti. It was not a feature I requested or even knew existed.
It sounds like a small detail, but it says something: the system knows when it has gone a long time without help, and it keeps count. On this trip the counter reset only once, at minute seventeen.
A real test is not a lab.
We passed an accident on the highway and FSD handled it without me doing anything. I mention it because it happened — but it is not shown on camera: I reviewed the full footage and nothing identifiable is resolved. It remains my testimony, not evidence.
This is not a laboratory test. It is a real trip, with my car, my route, and that day's weather. Another day, road, or rain may produce something different.
