FSD v14.3.4 SW 2026.14.6.11

It handled the rain. I was the one who hesitated.

Father's Day, in the rain, with a 'FSD degraded' warning on screen — and it drove like it was nothing. The usual doubts… and one where the one who failed was me.

Improvements (3)

  • Rain + 'FSD degraded' warning

    Heavy rain started and a 'FSD degraded' warning popped up on screen. It kept going as if nothing happened: held its lane, respected the lane lines, and didn't brake for no reason on the wet road.

  • Exited the narrow driveway on its own

    At the first house on the route, the car exited a very narrow driveway entirely on its own, no problem. Going in it was steering itself and never hesitated — I was the one who took over.

  • Auto-park waiting for the gate

    On the second stop of the day, it waited for the gate to be opened, drove in, and parked itself.

Known issues (3)

  • Exit speed bump

    Just like every previous version, at the speed bump leaving home I have to slow it down myself. It eases off, but not enough. This hasn't changed.

  • Exit crossing (4 lanes)

    Four lanes split by a median. Same as all of v14: it won't cross unless all four lanes are clear. On a main avenue that's nearly impossible, so you have to help it along by accelerating.

  • Final speed bump (same spot)

    To close the drive we came back to the same speed bump from the start — and again it needed a hand. Same spot, same detail.
