This thread has been dormant for a while, but I thought I'd share an experience from last weekend:

Rural NZ roads have a lot of short single-lane bridges. They are always marked on both sides as to which direction has the right of way if vehicles are approaching from both directions.

I was riding with DH and two friends when we came to one of these bridges. We had the right of way, and we all rode onto the bridge together. Nice sunny day, bright clothing.

When we were halfway across, a car started driving onto the bridge right at us. Didn't stop until we were a couple of feet from his bumper. We didn't give any ground (had nowhere to go in any case). We left the driver stopped in the middle of the bridge with his female companion apparently screaming at him--and three cars following us, so he wasn't going to get past them.

Didn't stick around to see what happened. I contemplated taking his number and reporting him, but he looked like he was getting educated already.
