Is it unethical to order food in, because the weather is too unsafe to go get it yourself?
in fact, the question itself is somewhat unethical, because you are presuming to make value judgements on behalf of other people (the deliverypeople). I'll be a little more generous if you've done some kind of survey in order to have a statistical understanding. But we must assume that the other people in this world are rational actors, or go mad trying to save them.
P.S. - When it freezes and/or snows in Austin, I take a taxicab to work. It's like being the star of some ponderous, slapstick-tragicomic automotive ballet.
