What, you breathing hard? Well that not a speed workout, that a fartlek workout (and a pretty bad one at that, with intervals that short). Chances are you have to go through a learning curve of knowing how to pace yourself, because if I go out too hard in the first 200m of a 400m interval, I do hit the wall, and that will mess up all of my future times. I not disagreeing with you, people do Tabata terribly, and yes, a lot of people don actually know how to go all out..
