I guess I've never noticed before, but if you put the wipers on intermittent fast speed, they go faster if your moving and slow way down if your going slow. Seems like 20mph is the dividing line. 95 LS400
never knew that! i did notice that when you squirt the windshield washer fluid, the wipers wipe twice, then pause then wipe a third time to get the excess drip! brilliant wiper system on such an old car!
I noticed with mine, if I have the intermediate delay in slow, and the wipers on low, when I come to a stop the wipers will go into intermediate, then when I let off the brake it goes back to Low speed.
