yeah thats a little nuts...you don't have control...Thats the difference between fixed and this nutter...we're in control..
Funny enough I was at a LBS the other day with a few other Bikeforums guys...there was a wrench there, who had a SS MTB that he rides brakeless too...He jams his shoe between the wheel and the bike to slow down....like we did on our BMX's when we here kids!
