A word that represents both getting on and/or off of something (in general)

Is there a single word or phrase that exists to represent the action of both getting on and/or off of something such as public transport in general?

I understand there are words like ingress/egress, embark/disembark, ascent/descent, board/deboard, etc. but these only represent one or the other.

Solution 1:

English has no specific word for "I inverted my state of possibly being on a vehicle." You'd have to either use a specific word like "board" which means only on or off, or else you'd have to explain and set up a really specific unusual context where a reader could understand a very generic word like "changed" to mean what you want.

I could imagine a book trying to set up something like that, but it would be a literary device, and probably only used to talk about a character being really bored or numb so they don't pay attention to what they are doing. Not a standard way of talking about it.
