Phhh I dunno, sounds like a lot of effort

Anyways, I doubt it will happen, I mean making a whole city or country drive on the opposite side one day wouldn't work too well. There'd be people who didn't get the message, and some that forget, plus don't forget all the cars already RHD. Anyways, I know you had to be joking (I sure hope you were lol).
Visibility on a 69 sportsroof isn't very good is it?, so I think that having LHD and bad visibility wouldn't be safe.
