> Walter Hancock's 1833 Steam coach > The weight of the original vehicle is not known but Tom Brogden’s replica (see illust. 001) built from the original drawings, weighs 3.2 tonnes.
> In 1872 a steam coach by Charles Randolph of Glasgow weighed four and a half long tons (5.0 short tons; 4.6 t), was 15 feet (4.57 m) in length, but had a maximum speed of only six miles per hour (9.7 km/h).
Подпрыгивание на ухабе — грубо прохождение небольшой окружности, усилие пропорционально квадрату скорости. Уверен что ущерб дороге растет нелинейно, а скорость паровых автобусов была выше.
Есть мнение что ущерб был и меньше
> According to engineers, steam carriages caused one-third the damage to the road surface as that caused by the action of horses' feet. Indeed, the wide tires of the steam carriages (designed for better traction) caused virtually no damage to the streets, whereas the narrow wheels of the horse drawn carriages (designed to reduce the effort required of horses) tended to cause rutting.
но источника в сети нет, я подозреваю там тупо взяли удельное давление, что не совсем корректно.
