I’m no expert, but I walk a lot. I walk on the left to see approaching cars, Amazon trucks, carts, bikes, etc., then I may cross over to the right to get out of their way. The side I walk on depends if there is room to move off to the side. Many paths have landscaping right up to the path, like near underpasses. Then I walk on the right. So many of our roads and paths have a hump, that my hips appreciate me walking so one leg doesn’t get longer than the other. : )
I prefer the left, but judge my surroundings. Besides, when you are looking at the traffic ..you can wave and see if they are on the phone.
