I reckon I have shocked and drenched a few startled bystanders when I turned on my wiper on a wet day at standstill position. The force of the wiper action really "chucks" the water a long way off the side of the car instead of downwards or to the vertical edges of the screen. I've had a few unpleasant words directed at me due to this like f/words, s/words and others. Is this normal or the wiper is out of adjustment???
