I have seen a few examples where it is used to imply reckless actions with other intangibles: “Dash

into cash/stocks/bonds” appears as headlines talking about investment.

What has the queen considered from “The US Government’s headlong dash into Brexit”, “Australia’s dash into military war in 1914 was no knee-jerk response”, “she thinks if I’m really in love I’d dash into marriage like a mad thing” describe changes of state rather than physical places.

As “dash into” is so much more commonly used with real things or locations, that “I dashed into my homework” would only be used literally. “I dashed into my homework, knocking my books to the floor”.

In the UK military parlance, unmanned aircraft are or are ‘uninhabited aviation vehicles’. Is it unusual to say someone ‘inhabits’ a desk?

Can ‘unmanned’ mean ‘cowardly’ (see phrase in unmanned by fear), rather than manned or two?
