A recent posts from +Interesting Engineering
shows the road space required to transport 60 people. It is meant to demonstrate how public transport and cycling reduces traffic. While true, the images they used to demonstrate this have worked to undermine their credibility.
The top image is the original which exaggerates the space taken up by cars, the image is taken from a different perspective and zoomed in.
The lower image is one that I've corrected. A perspective and scale correction was applied to align the buildings and overlaid it on the bus photo to give a more accurate comparison of the space required. It still illustrates the point but now it's more credible.
