Went and drove around the lot for a bit. First time I've been there in years and I forget how big it is. Didn't see any sign of construction going on.
There was a fenced off area on the east side of the underground lot but I think that was more for Ikea storage rather than Tesla.
One question I do have is aren't these lots typically closed/gated after hours? I sort of remember that being the case when they opened long ago but maybe that's changed.
