I think you’re correct that some Swindon made Hondas end up in the USA etc.
And yes it’s probably not only Brexit, causing this but the effect can’t be written off.k
More than just “some” - my understanding is that over half of Swindon’s production goes to North America. If that’s the case it would be daft to contemplate keeping production in the UK when the current Civic ceases.
Why ?. 
Especially if our government removes quota,tariff and EU type approval barriers from US vehicle imports and hits Jap and EU imports instead.With pressure from the US on the Jap government to keep Jap export,US market,car production in the UK being a fair part of the deal.The whole scam looks like an amateurish attempt by the EU ( Germany ) to play off the Japs against the UK which Brexit would allow us to throw back in their faces by playing off the US against the EU and the Japs.
