it appears that when the intermittent wipers are set to their quickest setting, they will speed up when driving street speeds and slow down when driving parking lot speeds. i have been able to reproduce this no problem. basically, when you are in the parking lot, they wipe once a second. as you pick up speed, they go to what appears to be normal speed. also, when you let your foot off the brake after a stop, they do a quick swipe to ready your windshield for driving. pretty slick!
