“A bicyclist claims I almost ran him over. I didn’t hit him, but he fell over and made sued my insurance company. He claims he was at the right side of my car as I was merging towards the right to make a turn. If he was indeed in my blind spot, then it’s important to note that the blind spot assist didn’t alarm and that the design of the passenger seat does create a blind spot, especially for someone of short stature since I cannot see over the passenger seat. …”
