My area of Austin is generally taking it seriously although when I do go out for grocery pickup traffic seems to be getting slowly back to closer to normal, so I think patience is slowly eroding. From what I've outside of the city in more rural areas is that probably 75% of folks there are acting like there's nothing unusual happening at all (to be fair, in some places they're right).
I suspect it's quite different from city to city, and even neighborhood to neighborhood in places like Austin and Dallas. My zip code is really low in infections, but the one just south of me (which is significantly different from my zip code not so much demographically but economically) is one of the two worst in the county. I bet if I went to the dumpy old HEB down there, it'd look different.
