It was pouring by me yesterday and I stopped at a traffic light with the wiper set to either lo or hi. I then noticed the car was rocking left and right. Anyone else noticed it?
My 1850-lb Insight nearly tips over it rocks so hard when the wipers are going. Our heavy Clarity also rocks, but a lot less. Interestingly, I believe the Clarity has a separate motor for each wiper, so there's not as much reciprocating linkage, etc. as in more primitive cars that use only one wiper motor.
