I live in Scotland…now as you’re probably aware, we have a fair few double decker busses buzzing in and around town. Now these things would be id say at least 2.5 metres wide, between 5 and 6 metres high and around 10/12 metres long. Now these vehicles manage to corner 45-90 degree bends at speeds varying between 20-40 mph. When doing this, you can clearly see them leaning (quite substantially I would say) but never to my knowledge has one toppled. I have been informed that this is due to its low centre of gravity, but have always wondered what gives it this low centre of gravity? Can anyone shed some light plz?
