This morning I had a cyclist do a particularly silly thing so I thought I'd highlight it. This cyclist made her way up the left side of my vehicle while I was indicating to turn left at a roundabout. I knew she was at the back of the vehicle as I was waiting my turn, when I was able to enter the roundabout, besides seeing and reacting to a car shooting through the intersection, I scanned the FOUR mirrors on my left side and she was gone! Only a second before she was still clipped in and at my back wheels, guessing that she was now in my blind spot beside my front left wheel I hit the picks and then the horn. As you can see in the video, she just rode around the corner, only looking to see if there was something crossing my path.
She's an ignoramus.
It's illegal to overtake a vehicle on the left. It's illegal for a cyclist to overtake a vehicle on the left if the vehicle is turning left.
