I didn't know where to post this since there is no Model S or Model Y thread that I could find.
Anyway when I first saw this I checked my calendar to see if it was April 1 :-)
Of course it's UK only since you are allowed to drive LHD cars there with no issue. But for other RHD drive markets like Australia or Japan (don't include NZ since you could never buy a Model S or Z here from a local showroom) they are going to be out of luck.
