Car Trunk vs Car Boot: A clear win for US English, trunk was already a thing in which you stored items, frequently for transport.
Crisps vs Chips: I gotta admit, the Brits have this one. They're thin slices of potato that have been made crispy. No chipping of any materials involved.
Car Park vs Parking Lot: Equally matched. What's a car park? A place to park cars. What's a parking lot? An otherwise empty lot where you can park.
Elevator vs Lift: Both equally fail to address that the damn thing also goes down.
