This is obviously a very congested narrow roadway with a blind curve for added difficulty. Truck was driving beside parked cars and most likely needing to squeeze a gap in the traffic. His viewpoint would be very NARROW as well. You can't see nothing coming in the lane beside until you creep ahead, like going thru a line of stopped traffic.
I had a situation like this just 2 days ago while going across a 6 lane avenue in light traffic after supper. A big pickup turned on his light to turn right to this narrow residential street. He just stopped there for some reason. I started out cautiously and sure enough a car was hiding alongside. He said something to me after the car went by.

Then back the last day in grade 9 this happened while walking from school, a taxi laid out a 30 foot trail of rubber and the 2 people yanked their heads around to look at me. LOL. My brother's friend was watching from across this same 6 lane ave.
I had my full heavy briefcase in my left hand.
