I walk fast. This is because I am a decent human being, unlike all of the people who waddle in front of me at 1 mile per hour, like they have nothing to accomplish in their lives except be obstacles to human progress.
The city of Liverpool, UK found that 47% of survey respondents said that slow walkers are the most annoying problem they encounter when shopping in the city center. The city responded to this problem by making it legal to taser slow walkers building "fast lanes" on sidewalks with high foot traffic. The Independent reports:
Opening on the city's St John Street, the fast lanes will allow users to speed through the crowds while perusing the three-storey Liverpool One shopping centre.
The research, conducted by Argos, also revealed shoppers hated battling through crowds, people chatting in the middle of the street and pavement hoggers.
I found this article through reddit, where commenters offer great suggestions about how to deal with slow walkers. For example:
I find it's much easier to trip them or push them to the ground and continue my walking without the awkward baby steps behind them. Try it for yourself
