let me elaborate on my hasty response. if you are practicing trackstands in a parking lot, after a while you'll get it down so you'll be almost motionless. in some traffic situations, you might attain this form, too. however, there will be situations in which it will be more difficult to achieve that form (e.g., a busy intersection on a downhill in which you must keep your eyes on three things at once). in these situations, i'm twitchy, but still in control.
