So I'm pretty sure I just found the dumbest person on the face of the earth.
They've been doing a lot of road work in the area around my school. They're putting in new gas or sewer lines or something. Everyday there's a new stretch of road that is closed off.
I leave school on my lunch and come to this intersection about 1/4 mile from my school. I'm heading south and wanting to turn left/east. I get to the signal and there's one car ahead of me in the left turn lane. The green arrow comes up but the car doesn't move. I give it a second and then honk my horn assuming the person just isn't paying attention to the signal. The car still doesn't move so I honk again. This time I can see the driver lift up their hands like "what am I supposed to do?".
Now the street we are both in line to turn on to is being worked on. There are two lanes in either direction and the construction guys have the 2 eastbound lanes blocked off. There's about 10 guys working with a big backhoe thing and one of those mini steamroller type deals. There's also a big "detour" sign directing people who want to head east to use one of the westbound lanes. The two westbound lands have been coned off so that one can be used for eastbound traffic for about 1/2 mile.
So the green arrow turns red while the car in front of me just sits there. I'm not in a huge hurry and I just figure it's not a big deal to wait for the next cycle. So the green arrow comes up again and the car in front of me still doesn't move. I honk again only to have the driver

at me again. So now I'm thinking that the person in front of me might be having car trouble. I decide I'll be a good Samaritan and see if she needs any help. Besides she might be a parent of one of our students or something.
I get out of my car and walk up to the driver side door. She sees me coming and rolls down her window. It's a woman about 30. She's driving a brand new white SUV. I ask her "Are you having some trouble with your car?"
Her: (frustrated) No. I just can't go anywhere with those guys in the way.
Me: The construction guys?
Her: Yes! They've got half of the road taken up with their equipment!"
Me:

Um...you know you can still head down that street you just have to use that lane on the left.
Her: No I can't. That's the lane for the people coming the other way!
Me: Oh...actually they've got one of those lanes sectioned off so that you can still head east down th...
Her: THAT IS THE LANE FOR THE PEOPLE COMING THE OTHER WAY!
Me: Yeaaahhhh. You see that detour sign and all of those cones? That means they set it up so you can use the 'other' lane to go that way.
Her: BUT WHAT IF SOMEBODY IS COMING THE OTHER WAY! I DON'T WANT TO GET HIT! THIS IS A NEW CAR!"
I think about saying something else but figure it's not going to do any good. And by that time the light had cycled back to red and almost back to the green arrow.
I just walked back to my car. Then I waited for the light to change, swooped around her, and used the detour lane. She could still be sitting there for all I know.
