Tesla driver here.

When I first heard the announcement that they were going vision-only, I thought ah shit they're boned.

I replied on maybe a Reddit thread (?) that there was no way it'll work up north in any kind of snowy conditions, and people called me an idiot etc

Fast forward a few years later, when I got to experience it first hand. Anytime I drive the car at night, warnings pop up on the screen like "front left camera is blocked or blinded" Cue Surprised Pikachu. In the snow, sometimes it can't even detect a road.

I tried the free trial of FSD and, while it's a neat gimmick, I think I was able to make maybe one or two short trips (2km) without needing to disengage it.

It was really bad
