AnnaS; I too have had that link bookmarked for some time. Fascinating information on how the sides for driving were chosen.

My brother-in-law has a 1928 Crossley, the Gentelman's Sports model in which the only sporting thing about it is that the back of the bench front seat folds down to make a double bed. A magnificent vehicle, but requires great care in driving because the pedals are not in the standard configuration of A-B-C but (I think) A-C-B.

And on the left-right etymology, it's quite simple (with apologies to lefties); the right hand is the one you write with and the left is the one left over.
