I'm suspicious that mine doesn't happen all the time, although I need to do more specific tests. I tried it earlier and it didn't go left at all, but I also only accelerated to 60ish. On the highway is when I can notice it the easiest, just accelerate heavily from 30-70+ and you'll end up in the left lane.
When they 'fixed' the alignment with only 13K miles on the car, it suddenly went perfectly straight (from ~4-5 degrees off center to 1 degree), but the pull left issue is almost identical before and after. I'll still end up in the left lane, but maybe it'll be 6 car lengths instead of 2-3.
My next step is to switch back to my old tires and use those for a few thousand miles to see if it's still going on. After that I might take it to a local enthusiast shop and explain the issue, see if they have any interest in really trying to perfect the alignment and rule it out. Don't really have any game plan beyond that, Tesla service told me they weren't interested in helping with it
