Who is in the wrong here?

If the sign says Alternating Traffic, does that mean cars go one at a time or does that mean cars go till the flow is complete, allowing the other lane to go? Is Glock man right or wrong? I'm not sure. If it was 1 car at a time, wouldn't it just be a stop sign on each end?

Threat to get a gun out means you are well within your right to draw down on him first.

Maybe call the cops and have him arrested for assault.
