My '91 MkII Golf had programmable wipers... as in you could set the delay. Press once for on, then again to set at desired delay. Best part was, it was just a relay so you could grab one from any old pick 'n pull and upgrade yourself!
On the other side, Rain-sensing wipers are the devil... always too fast or too slow at the wrong time... you can toss them in the garbage IMHO.
