>Parking one's bike in sleepy Northampton, taking a nap, then waking up in Manhattan without having to find parking is a dream.

Or reading a book or playing a computer game or writing your own book or learning how to edit photo with Gimp or enjoying the scenery outside or ... ANYTHING other than clutching a steering wheel, staring straight ahead, and hoping you get there without an accident. 4+ hours of doing whatever you want always beats less than 4 hours driving.
