I don't think the car that hit Venus was speeding. At the very start of the video, you can see cars in that same direction going by pretty quickly and it looks to be going about the same speed as the car that hit Venus. I also think they may not have seen her considering she was in the back end of the intersection most of the time, then let the car turn left when she had the right of way, and then went through the rest of the intersection. The 2 cars that stopped on the same direction as the car that hit Venus seemed to only stop because the car turning left was going, as if they already had a green light. I think because of Venus stopping for no reason in the middle of the intersection when she had the right of way, it delayed everything by 3+ seconds. Also, when you are waiting to turn left on a solid green light, you control the intersection. The car that hit Venus may have seen that car controlling the intersection turn left as their light turned green, which would make you think the intersection is now clear, and then Venus continued driving through the rest of the intersection.

I just don't get why she let the car turn left before she passed through.
