ELI5: How do zombie/survival movies like 28 days later make cities look so empty?

Do they have to close off entire districts of a city to film the movie? What about busy roads in an overview shot, wouldn't you see cars driving all over?

I believe they cordon off business districts during the weekends it's easy enough to do since they are mostly closed, for the cars just edit them out if you watch survive the walking dead when they are in Mexico you can see a car driving in the background in one of the shots.
