I ran into a couple of other E owners in a coffee shop retreating from a downpour. We started talking and ended up sharing that we all had the experience of almost changing lanes into a car because of the blind spot on the driver's side. I already put a spot mirror on mine and it's much safer. One of the other E owners was going straight to the auto supply to get one. I think because what used to be called a pillar between the front and back windows is so large on the E it really is kinda dangerous. If you haven't put one on already please do.
