I agree, having driven up and down it in a family car a number of times. The turn into Rotcher Lane is rather tricky too. I may walk up there some time and measure the width.
Just to confirm, there's no gate or any obstacle other than the width and tightness of bend, and there's no legal prohibition or restriction. I believe it to be a public road. I don't recall there being any signs at all but I'll check that too when I'm next there.
