Yes, hostile architecture does sound exactly like the “solution” they’d go for. I hope I didn’t imply the wrong thing; I think fences in conjunction with adequate crossings is the answer.

Thinking more about it, I don’t think we actually have jaywalking laws here, or at least they aren’t enforced in town. I should hope there’s some kind of rules about being a hazard in busy traffic, but everyone walks in the street in town when cars and bikes aren’t coming, right in front of police even, and I think that’s very reasonable. Many streets are only open to buses, taxis, and delivery vehicles, so it’s quiet and safe.
