It wouldn’t. Nor would it be unsafe. These property value fuckers are not just obnoxious but also really stupid.
There’s a neighborhood in my city right next to a light rail station. Literally, some of the houses are less than 20m from the platform. But when the station was being built the neighborhood association specifically campaigned against having any access to the station from the neighborhood. There’s a huge concrete wall blocking it off now. So if the people living in the houses literally directly next to the station wanted to get to the station they’d have to walk (or realistically, drive) over 2km across a highway, along a major road and through busy parking lots. And then, after getting to the station, they’d have to cross back under the highway to get to the actual train platform, because it’s built on their side of the highway despite being impossible to get to from that side.
It’s also dangerous to walk outdoors at all. I saw the aftermath of a drunk driver killing a pedestrian at 6 AM a few days ago. There was debris spread for at least a hundred meters down the road. The news said the driver was uninjured.
