jinricksha, rickshaw, (kokuji)
俥 centers on a human-drawn wheeled vehicle: a rickshaw or jinricksha. It is a kokuji created in Japan to represent this specific type of cart.
俥 is a Japanese kokuji combining 亻 (person) and 車 (vehicle), directly representing a person-pulled cart or rickshaw.
A person 亻 beside a vehicle 車: imagine a runner pulling a two-wheeled cart, which is exactly a rickshaw.
For くるま, picture the rickshaw's wheels turning as it's pulled: くるま sounds like 'kuruma', the Japanese word for car or wheeled vehicle, making it easy to remember this reading for a person-drawn cart.
