Word for anyone inside a car or bus, both passengers and driver [duplicate]

In English, we would call those occupants:

occupant noun

a person who is in a car, room, seat, place, or position:
_{One of the occupants of the car was slightly injured.}

_{Source: Cambridge Dictionary — occupy}

Here are some examples from the Corpus of Contemporary American English for vehicle occupants:

I'd suggest occupant

noun:
a person who is in a car, room, seat, place, or position

• One of the occupants of the car was slightly injured.

Cambridge Dictionary

Possibly occupant:

a person who is in a car, room, seat, place, or position.

In a terrific accident all four occupants were killed.

The U.S. airline industry uses “souls on board” in emergencies, which is more inclusive than passengers and crew, since some people on board may be neither. It does not include cadavers, animals, or unborn babies.

I agree that “occupants” is good for this purpose.
