To the woman I almost met with my car...

That thing you blew by on the access road as I was exiting the highway is called a Yield Sign.

It lets you know that you need to yield to traffic exiting the highway. If the powers that be had wanted you to merge at that point in the roads they would have placed a Merge Sign at that location instead of the aforementioned Yield Sign. Actually, a Merge Sign might have forced you to acknowledge the cars coming off the highway.

I guess what I'm trying to say is that you have no idea how close that Yield Sign was the last thing you didn't see in your life.

Maybe though in the future you will.
