Fast quick: whatever that means, Tesla’s mad for it.

English can be a funny language. Usually, “to go really fast” and “to go really quickly” just mean the same thing. But “to go really fast really quickly” means something quite different.

Similarly, insane – which derives from the Latin “in”, meaning “not” and “sanus”, meaning “healthy” – now has as its official principal meaning “not of sound mind”. But actually, it’s often used in quite a different sense. For example, in Tesla’s new “insane mode”, which has gone viral (another phrase that doesn’t mean what it used to).

That first version is it without the earthier words in the English language which you might want to avoid at work, or if there are children about. If you want the full-on Anglo-Saxon version, it’s here.
