There's a 3-lane road that I take on my way home from work that forks, with the left lane splitting off from the two right lanes. It's the type of split where, if you don't know to expect it, it can throw a lot of people off. It's also common because of other traffic patterns for people to end up in the left lane even though they want to go off to the right, so there are a lot of people who do move into the middle lane from the left lane. Most of the time, though, that move happens well before the road actually forks, so it's not a big deal as long as they aren't being jerks.
Yesterday, though, there was a van that swerved into the middle lane right in front of me, like 5 feet before the road finished splitting at the fork. If I hadn't been paying attention and/or didn't have really good reflexes, the van would either have plowed into me or the median. There was literally no indication before that that the van wanted to be in my lane, so it was pretty scary.
I kind of dismissed it as someone who is from out of the area. There are a lot of people who drive here who are from out of the area, and a lot of the things streets do here legitimately make no sense. Plus, there's a very real lack of signage for a lot of them. So I try to remind myself that not everyone drives this route every week day the way that I do and let it go as long as nothing terrible happened.
But later, this same van turned off the road we were on, and I saw that it was a courtesy van for a local car dealership. The dealership is pretty close to the area where this incident happened, so I'd be surprised if the drivers didn't encounter it on a regular basis. Given that it's someone who is definitely local, and is most likely employed specifically to drive places, and that the area is one any driver likely encounters frequently...I call special snowflake. I'd have called somebody to report it if I had the license plate number, but alas, I do not. So I'm going to let it go.
