From page D10 of July 11 Saturday/Sunday Wall Street Journal’s Dan Neil auto review:
Sample quote
Postscript: You mat be wondering how to keep your SUV from becoming an eight passenger super-spreader. First, experts advise, crack a window. A study by the Harvard T. H. chan School of Public Health showed that opening one car window 3 inches can produce a ten-fold reduction in the amount of virus in the cabin air. The authors also note that modern cars are tightly sealed against noise, wind force and outside air. If you need to run the air conditioning or heat, turn off the recirculation air function to bring in fresh air. And, obviously, everybody wears a mask or they walk to school.
