As usual for this time of year there are a number of people on the road with their lights off. What's your preferred way to indicate "politely" to the other driver so they turn their lights on.

I've tried to help two drivers recently who were both very confused why I was

• Honking
• Flashing my headlights
• Slowed down in-front of them with my hazard lights on
• On arm out of the driver window with my hand "flashing" - open/closing fist.

With one driver I tried the above with no luck and then they proceeded to give me the finger when I matched their speed and tried to get them to roll down their window so I speak to them. The drive proceeded to speed off and I finally noticed a couple of minutes later that they'd turned their lights on.

About the only time drivers take notice of a headlight flash is when they think a police speed trap might be ahead.

So what's your experience and any tips for dealing with NZ drivers?
