You know, I get that too. I commute in a VERY SMALL TOWN in southern Florida where everyone is ELDERLY and driving a pickup truck. Because I'm NOT in a pickup truck, many people don't seem to see me, or care to. Today I was commuting on my regular route at my regular time. I came to an intersection and slowed for the pickup truck coming from my left, and then made a right turn behind him, an elderly woman coming from the other side of the intersection (facing me) also waited for the pickup, ignored me, and made a left hand turn into the lane I was traveling in. I saw her coming, and grabbed brakes, but it was plain that she did NOT see me. I run a strobe on the front of the bike, it is VERY bright, but if you aren't a pickup truck or huge SUV in this town, you are invisible! I wrote a letter to the editor and it was published last week, but no one read it (I'm sure). So, as commuters on bikes we have to keep our eyes open and react for every zombie driver in a cage that is out there.
