A shopping mall could have screeners at literally every entrance, and there are sometimes dozens of entrances at a shopping mall. Even then, traffic might be reduced, but it would be enough traffic for something like regular life to resume. Some businesses would be able to survive, even if not all. * IDEA * They could also do checks in the parking lot of any business. You drive up, someone comes out to start the process and marks down your license plate. After 10 minutes they return to your car and tell you your results. This way nobody is standing in long lines possibly spreading the disease to each other. And it scales well to large numbers of people being tested simultaneously. There would be a lag time of 10 minutes, but throughput would be nearly the same as before COVID.
