How do you get other people to turn on their headlights?
I've noticed a disturbing trend during my long travels back and forth through Pennsylvania, Maryland, and Ohio: too many drivers refusing to turn on their lights on the highway. I've tried flashing my lights on and off, flashing brights, but nothing works to get them to realize their lights are off. It's dangerous for that to continue, but wracking my brain I can't figure out what else to try. I doubt honking would work... What do ya'll do to get people to turn on their headlights at night?
