I've always approached motorcycle riding with the position that sooner or later I'll run across an idiot and I need to be prepared for that. However yesterday I was treated to a whole new level of stupidity. As I was traveling westbound on a two lane road which had a center turn lane I activated my right turn signal and shortly after began braking for a right turn into the parking lot on my right hand side. It's important to note that there is no curb between the parking lot and roadway at that location. The driver behind me felt that this was some type of signal from me to pass me on my right hand side. I first saw him in my right mirror and instinctively turned my head slightly to the right to see him pulling along side at about a 45 degree angle to my cycle. Fortunately he seemed to realize that what he was doing might be unusual and decided to pass on my left side instead, utilizing the left turn lane for that purpose. Wow. That was a close one.
