I'm running FSD v13.2.9 and waiting for v14.x to be released, which is coming hopefully soon-ish. I'm not in major rush though for reasons you'll see below.
This is a personal anecdote, so take it for what you will. My current FSD actually self-drives today and has been for a very long time. It'll take me from my driveway to my work parking lot and back home without a single intervention. To get to work, I drive through country roads, city streets, and 2 highways. One of which is the busiest highway in North America.
I drive to work every day (M-F) and I can't stress this enough: I can't remember the last time I had to intervene . It's navigated road construction, the odd garbage truck stopping with no notice to pick up garbage bags on the side of the road (every Thursday morning around 6am), other drivers making last minute multi-lane changes to get to the highway exit, even drivers who brake check because they don't like the Cybertruck. I have a Model S too and have never been brake checked in that so *shrug*. It's deviated automatically from the regular route when it's detected there's standstill traffic somewhere along my route and then driven me home, again no intervention needed from me.
I've driven through fog, heavy rain, and unlit streets. My experience with FSD has been as flawless as I can expect. Of course, that is not going to be true for everyone, but when is anything every universally true when it comes to a persons experience of technology?
