Does FSD slow down at night due to limited visibility?
Unconfirmed: A Reddit user describes a nighttime trip of about 50 miles (approx. 80 km) from Austin to an overlook near Kingsland, Texas, in his Model Y, mostly on single-lane back roads with many curves. According to his observation, both with FSD and in standard driving, the car slowed down when forward visibility was limited by darkness or the winding road. He asks whether he is imagining this behavior. The post includes no software version, telemetry data, or response from Tesla.
- Nighttime trip of ~50 miles between Austin and Kingsland, Texas, in a Model Y.
- User says FSD slowed the car for darkness or curves; no official confirmation.
🔎 Why it matters: There is no official confirmation: it is one user's perception of a Model Y using FSD on a specific trip. The claim is that the car reduces speed when forward visibility is limited by darkness or curves, which the post does not document with data.
📈 Upside: Not applicable.
📉 Risk: It is unknown whether the speed reduction responds to headlight visibility or only to the road's curves.
