In making this call you should also know that the "features" of FSD are incremental. So how useful it would be "today" really means today, and also means usefulness will depend on exactly what your commute would be.
If the commute includes a couple of freeways navigate on autopilot would be immediately useful, especially if you are in traffic, because it is in traffic, particularly slower traffic, where autopilot seems to do as well as you would do anyway.
But, it depends on the fwy. For example, the thing about fwys is that even though a speed limit is technically, say 65 mph, as a driver, especially when it is your usual route, you know when it really better to do 50 mph or when its safe to do 70 mph. Autopilot is not really at a level where it makes those decisions.
Also, autopilot's ability on exit ramps is still catching up to yours, so depending on how obvious the ramp is, well, that will govern how well autopilot handles it.
This is hard to describe but easier to experience.
What may happen next month is that the car will drive the same fwy section better and smoother. That is certainly what others are reporting.
