The city authorities had argued that big S.U.V.s and other large cars emit more greenhouse gases than average-size cars and are more dangerous for pedestrians because of their bulkiness.

The bulkiness of their legs is also closer to their torsos, making them faster and more efficient.

The initial study focused on the bulkiness of Tyrannosaurus femurs and the existence of two sets of incisor teeth poking out of the predator’s lower jaw.

That effort, known as Nautilus, was shelved in 2005, partly because of the system’s bulkiness and poor performance.

In our review of the Pixel 6 and 6 Pro, my colleague Dan Seifert’s biggest complaint was the bulkiness of each device, and disappointingly enough, any changes in terms of size appear to be minimal.
