In what way are the the wipers set for lhd models?
They look the right way for rhd to me.
The driver's side (rhd) wiper ends it's wipe with the blade parallel to the A pillar which is best for vision from the driving position.
You are quite correct, sweeping to the A pillar is how it should be. But several car makers had the drivers side blade sweeping flat to the bottom of the windscreen instead on some models, leaving a blind spot on the top and right of the screen. The early Marinas actually had the correct pattern, but adopted the other pattern soon in its life. "Motoring Which" a publication from the Consumers Association took this up with British Leyland, the explanation they gave was it helped stop the wipers lifting off the screen at higher speeds. BL wasn't them only offender, most Triumph saloon cars (before it was part of BL), and the Hillman Hunter also did the same thing. Export lhd versions also had the drivers side blade sweeping the "wrong" way for the driver.
Many imported cars were sold in this country without the wipers set for rhd at the time, most Renault cars, the Peugeot 504, Volvos, and probably the worst offender, the BMW 1602/2002 are some I can think of in a hurry.
