Chips, meaning fried potato pieces as opposed to fried potato slices, were being made in the UK and Europe a long time before being named "French Fries" by Americans. "French Fries" are now made from reconsituted potato pulp extruded into shape as opposed to pieces of freshly cut potato. Although you do get US "French Fries" in the UK. UK chips are normally quite unlike "French Fries" served in US fast food style establishments. Typically on UK menus it will say "Fries" or "French Fries" if you are not getting chips. For the record, the best chips I've had come from The Netherlands, Belgium and Yorkishire, England in that order.

I wonder whether there is any objective evidence for the usefulness of text written on the road surface, as opposed to road markings (the old-fashioned zebra crossing, stripes) and/or road signs. In Melbourne, at least in the areas I frequent, we don't have many examples of text written on the road surface myself. But when I do see them, I find them more distracting than helpful. -- Steve “Cheer up,” they said, “things could be worse.” So I cheered up, and sure enough, things got worse.

I know some writing is written right to left and some is left to right and some is top to bottom but I've never come across bottom to top! ;-)

In the United States, ambulances often have their signage written backwards so that it appears normal in a rear view mirror.
