Promised drive-through testing sites haven't materialized

Two weeks ago, President Donald Trump promised a network of drive-through covid-19 testing sites across the country where people could be tested "very safely, quickly and conveniently." In a Rose Garden news conference, chief executives of Target, Walgreens, Walmart and CVS said they would work with the government to provide space in store parking lots.
While the four retailers have a combined 26,400 U.S. stores, this vision of a proliferation of coronavirus testing sites has yet to materialize.
