Whatever our human laws and morality says about right and wrong and fault, the laws of physics usually judges the car a winner when it hits somebody.
Placing yourself somewhere where pedestrians are not expected (non-residental road) mostly hidden from oncoming traffic for an extended period is putting yourself in undue risk.
You'd be legally right, dead right.
I walk that road many times. I hug the side on the outside of the turn (there's no room on the inside) and so I can see (and be seen) from further away. I listen for cars coming. I watch for them. I am prepared to jump over the railing.
It's just common sense.
BTW, do you know that if you rear-end someone, it's your fault? I once was in heavy traffic, and the traffic in front of me stopped abruptly. I hit the brakes hard. I also glanced in the rearview mirror and realized the truck behind me was not going to stop in time. So I quickly pulled onto the shoulder. The truck hit the car in front of me.
But fortunately, that gave the truck a precious few more feet of stopping distance, and the collision with the car in front was minor.
Last year I was driving on an arterial, with a 35mph speed limit, that was a miles long downhill grade. There was a bike lane on the right. In it was a girl maybe 12, and on the back of it was another girl maybe 6. With the downhill, she was able to go about 20mph. Suddenly, she veers into the center of the car lane. Never looked over her shoulder. (Traffic was lining up behind me.) She then rides a bit on the stripe separating the bike land from the car lane. Then back to center of the car lane. Then in the bike lane, then back to the car lane. Back and forth. She never looked over her shoulder. I never dared to pass her, even when she was in the bike lane.
OMG
You don't always have a choice about where you are momentarily and anybody turning a blind corner has an obligation to immediately reduce their speed (prior to turning the corner!) to where they can safely come to a stop without endangering others. That's drivers education 101. Right after 'don't text while driving', 'don't drink while driving' and 'slow down when there are pedestrians, bicycles and other fragile road users around'.
