John, I 'm also left-handed and suffer from this same driving condition. It's a long-running joke in my family, though I notice it's not as much of an issue these days with Waze always on (which is pretty much a requirement for driving around LA). I did think I had some mild form of brain damage for a while (I still might), but I'm somewhat reassured that maybe it's not, as others such as yourself experience it also.
