It is not about whether it spreads virus, but drive-in theaters are there for satisfying social appetite. You go there with your family & friends - enjoy a movie outdoor. Otherwise, what is the benefit of that over watching a movie at home on a 60 or 70 inch screen?
Some people don't have 50-or-60-or-70-inch TV's, and even if they do, they might not match the experience of watching a movie on a ginormous screen (at a fairly high quality, too- I can see the pixels on my 45" 1080p panel I got secondhand from 15-20' away) and the sound systems at theaters are waay better than a soundbar and the surround sound at theaters local to me is orders of magnitude better than what I can put together right now as well.
