Leaf blowers are especially irritating in that it's far more convenient to make your leaves someone else's problem with a leaf blower than to actually make a pile (I don't want to say it's "impossible" to make a neat pile of leaves with a leaf blower, but I think it must require lots of skill, at least). But they don't actually solve any problem permanently, instead just moving the problem to tomorrow (or "right after the wind starts blowing again").
