IME it's not people with their lights on auto that are the problem, it's people who just haven't turned their lights on. Around dusk it may be that it was light when they started driving, and they haven't been paying attention. When I'm driving I can occasionally communicate the problem successfully by flashing my lights, but I'm usually on a bike, and it's almost impossible to get it across visually or audibly, and so they stay dangerous.
