Yes, but he's not looking at that, is he?
Assuming there's demand for Ford product elsewhere, there'll simply be a slowdown of RHD production and an increase of LHD. As it is, manufacturers can switch between LHD and RHD very quickly and I know that the MINI line in Oxford can do RHD/LHD/5door/3door/petrol/diesel - plus all the colour variants - all from the same line. I assume Ford can do the same.
