I don't think the doppler effect is as pronounced with a hair dryer as it is with a radar gun. For one thing, the hair dryer really needs to be plugged in, and even a gentle breeze can cause a false reading. There is a low conviction rate on hair dryer tickets.

See post #27. Apparently it's the heat that actually does the work.
