1) The driver can see a child standing directly in front of the bus. 2) People with less-than-ideal mobility (obese children, short or very young children, children carrying a heavy bag) don't have to clamber up or down stairs. See the link, around half the seats are step-free within the bus. That's a city bus configuration, of course it would be adjusted for a bus used only for school transport (no centre door, all seats facing forward etc). Alternatively, keep the centre doors and the child in a wheelchair can then take the normal bus with everyone else and not feel excluded — though this is a significant reduction in capacity assuming you want everyone to have a seat. https://www.avtobusi.com/en/mercedes-benz-city-bus/ https://www.avtobusi.com/en/mercedes-benz-city-bus/
