expressions - Why are you "On a train" yet "In a car" when you are inside both vehicles?
Why are you "On a train" yet "In a car" when you are inside both vehicles?
"On a bike" makes sense but "On a plane" seems wrong as you are actually inside the plane rather than on it.
Answer
Generally speaking, the metaphoric senses of get on and get in follow dimensionality:
- the object of on is a Surface, i.e, an object with 2 dimensions, or the surface of a 3-D object
- the object of in is a Container, i.e, a bounded 2-D or 3-D object
In terms of conveyances,
- humans get on a raft, a horse, a bicycle, a sled, a wagon, a skateboard, a surfboard
- humans get in a car, a boat, a ship, a railroad car, a trolley, a bus, an airplane
This much is predictable.
The problem arises with scheduled public conveyances; in that case only,
a human who gets in the conveyance physically
also is on the roster of passengers metaphorically
(on the roster is a 2-D "page/paper" metaphor).
So one can be said to get on the bus, the plane, the train, the trolley; but not the taxi.
