How sure are you about this? There's usually some kind of timer (and, sometimes, an assistant) to ensure that you wash for the specified amount of time.
Also, I always figured that scrubbing was essentially a precaution in case the gloves ripped or snagged (which, being thin latex, is far from improbable).
The "exam" gloves that doctors and dentists wear are typically nitrile, but I think most surgical gloves are still latex. I know ours are. The surgical gloves are longer, have cuffs, and come in a lot more sizes.
They are alternatives for allergic patients (and surgeons), but they're a little thicker and a bit more expensive.
