Me too.I always did drivers side. That way when I removed the top from the frunk I just pivoted & layed it in place & vise versa.
The perfect carmine always went in latches to the drivers side - and I am talking RHD. So since others are doing as I do - but in LHD cars, pretty clear it matters not.
Yes, same here in the UK - it's the only way all things being equal, as the latches would normally foul on the battery cover - if there's no battery cover, then either way around may well work. There was a thread or two previously on this. The picture here from the Bertone manual shows a LHD car even for the right hand market cars, which just resulted in some badly stored roofs with wear marks where the bonnet rubbed on them as they sat too highmine always went in latches to the drivers side - and I am talking RHD
