I was convinced cops purposely created traffic before I got my license

I got my license when I was 18 (25 now) but when I was younger I would be in heavy traffic with my parents I would always think that 2 patrol cars would zig zag on purpose slowing down traffic and then once it gets super backed up a cop sitting on an on-ramp would radio in saying “okay let them go” and traffic would slowly start moving. I only thought like this because I would never see an accident or no construction lol
