Yea had it happen to me, i was going out one day doing about 70, hit the water, ass of the van stepped out, turned into the slide and just put my foot down, watched the speedo spool up to about 105 before i managed to straighten out and get grip again. Bit of brown pants mania that day.
Have to say, all the roads on the way home i can tell you exactly where all the puddles of water are and all the dips etc etc
