I also now walk up a gated road, and sometimes get passed by vehicles.
In my case, I used to get a key from one of the landowners back there, so I'd be the one passing people that were walking/pedaling.
I never much appreciated the dirty/suspicious looks, and my look back probably made me look guilty.
I guess the point is: When there;s mixed ownership, various people can legally drive the road.
I wish I could still drive my old spot, but I can't begrudge those who can still drive it, and I can't tell who is legal or not. It's easier just not to assume someone's guilt.
Hope this helps.
And hope you get your bear.
