It's a good time to stop and take a drink.
This is a pretty good idea. That way they don't get upset because I didn't accept their gesture of kindness, but they still [hopefully] learn that they should just follow traffic laws because it gets *confusing*.
where I have had problems is crossing a main 4 lane where I have a stop sign and the main road does not. I have got cars stop in the far lanes and waiting for me to go when the near lanes have cars blowing by at 40mph. I have also seen the driver of the far lane car throw his hands up pissed when I wouldn't jump into traffic against the right of way to be killed.
Wow...I guess I'm lucky that this, so far, has happened to me only on smaller back roads. Yikes.
