"I'm on a car" and "I'm in a car" difference?

[Calvinator1]

does "on a car" means the subject is a passenger and while "in a car" means the subject is driving/driver of the car? :up:
I have some trouble using prepositions, help please?

No, both people are "in" the car. "On" the car would refer to sitting on the hood, or the trunk, or the roof.

Thank you so much Mike:up:

You're welcome, but there is no reason to post a separate message to say "thank you". Simply click on the "like" or "thank" button to register your opinion.

Some of these prepositions don't make a lot of sense.
We are in a car, but on a bus. We are on a boat and a motorcylce, but in a golf cart. We are "in" a small boat but "on" a cruise liner.

German has some tricky ones too.
