Direction indicators; yep, as Mark says, European cars have the stalk on the left regardless of handedness of drive. The last car I had that had the indicator stalk on the right was a mid-70s Rover 2200 (P6 design), replaced by a Ford Cortina mk 4 in the early 80s.
From the Cortina, through two Rover SD1s, a Vauxhall Carlton (the UK version of the European Opel Omega) and four Mercs - see previous discussion!
- all direction stalks have been on the left.
And all since the Carlton have been automatic...
