Not the safest way to travel
Some areas of the world use double-decker buses frequently, but they are pretty unusual in the United States. While double-decker buses allow for the transport of more people at once while taking up less room on the road, the concept was met with some resistance when it was initially presented.
The majority of the public’s concern was that the new double-decker buses would fall over, which seems reasonable. The designers of the double-decker buses, on the other hand, were aware of what they were doing. So, to prove that it wouldn’t topple over, they tipped it around 45 degrees in a public demonstration.
