I was on hasting turning left at a light. There was a car in the oncoming lane making a left and cars driving through the light in the lane beside him. I'm sitting there for awhile and see a break in traffic so I take it. I was surprised to see a car in emerge from what I guess was a blind spot of some sort. Because of the way the angles worked out I couln't see the car driving through behind the opposite car turning left. The car driving through was a lowered small car. We didn't come close to colliding but it just totally freaked me out that I didn't even see him for a second. I guess driving a large van and at a high seating position I assumed that I could see everything which isn't the case sometimes.
