I've been commuting on a Streetmachine for two weeks now. Only 8.5 miles each way but it is quicker than a DF. Motorists aren't a problem - the majority give a wide berth from the novelty factor!
Bin-man stepped out in front of me yesterday, forcing a sudden stop. Only problem was gravity taking effect before I could get my feet onto the road. Cue one new mirror and one unhappy cyclist. Bin-mans comment that "those things are dangerous mate" didn't go down too well before I let fly with comments about prats walking into the road dragging bloody great bins behind them without looking.
Still got a grin a mile wide and not a sore butt cheek in sight.
