Is a double-decker London bus might be in danger of rolling over?

A double-decker London bus might be in danger of rolling over in a highway accident, but at the low speeds of its urban environment, it's plenty stable. The track width is 2.05 m. With no passengers, the height of the center of gravity is 1.45 m, ris- ing to 1.73 m when the bus is loaded to capacity.
