OK, first let me say that I very much appreciate that I no longer have to mess around with laying roads myself. That does indeed reduce tedium. However, letting a brainless bot decide where to put the roads can have some pretty hilarious consequences. Sorry for not taking a screenshot, but I'm sure you've all seen it by now: roads everywhere, all looking like the scribbling of a crazed toddler on a sugar high. Makes me smile every time.
