Despite their benefits, it is essential to address challenges associated with timber litter bins. One concern is the potential for vandalism and the need for regular maintenance. While timber is durable, it may require more upkeep than metal or plastic bins. Regular inspections and maintenance programs can mitigate these concerns, ensuring that the bins remain functional and visually appealing.

Beyond threats of crime, bollards also set boundaries that guide vehicular traffic. By marking the edges of roadways, sidewalks, and bike lanes, they help delineate spaces for different modes of transport, reducing the risk of collisions. This is particularly crucial in cities where congestion is prevalent, as the clear demarcation encourages disciplined driving behavior and better overall traffic flow.

A manhole cover was accidentally launched from its shaft during an underground nuclear test in 1957. During the Operation Plumbbob nuclear tests, a 900-kilogram (1,984 lb) steel plate cap was blasted off the test shaft at an unknown speed and appeared as a blur on a single frame of film of the test. It was never recovered, but it likely burned up in the atmosphere due to friction. If the manhole cover had made it into space, it would have been the first known man-made object in space, as it pre-dated the launch of Sputnik 1 by 38 days. A calculation before the event gave a predicted speed of six times Earth escape velocity. After the event, Dr. Robert R. Brownlee described the best estimate of the cover's speed from the photographic evidence as going like a bat out of hell!^[27][28][29]

1. Safety Improvements The primary advantage of inset manhole lids is safety. Traditional raised lids can pose significant hazards for pedestrians and cyclists. Inset lids reduce the potential for accidents, providing a smoother surface for all who travel across them. This is particularly relevant in high-traffic urban areas where the likelihood of incidents is greater.
