Train Conductor
noun
Who drives a car with their palm? The 車 here actually comes from 電車, which is a train, making this person a train conductor. If you think about it, conducting a train involves a lot more palm action because of all those levers and knobs and big buttons, right? Yeah, let's go with that.
This is a jukugo word that uses the on'yomi readings of the kanji. You should be able to read this on your own.
車掌は、乗客たちを待たせていることについて、お詫びをした。
