Why are the sensors on hand dryers so insensitive?

I frequent a place which uses hand dryers and supplies no towels (talk about insensitive) to dry one's hands. There would be NO PROBLEM IF the sensors on the hand dryers were more sensitive and were not dialed in on some completely random spatial location the size of a microdot. PLEASE HELP!!!!!

Those hand dryers are true germ pools. Better bring your own towel with you.
