Consider yourself VERY lucky!
When I do use that intersection, I almost always witness a very close call, and that is why I try to avoid it if I can. There is actually much less of a problem with the two lanes merging together ~100 ft after the turn than there is on the turn itself.
The transgressions range from being a few inches over the line to going completely from one lane to the other during the course of the turn. For some drivers, it’s almost as if the lines don’t exist.
