Low-Traffic Neighbourhood. You’re right, it’s poor editorial practice not to define it at first use! They’re quite a live issue in Hackney at the moment, which is why they’ve assumed people reading their Hackney-based blog will know it, but they still should’ve written it out in full the first time.

Lowering limits does change behaviour on its own, but I agree that proper traffic calming would be best.

Prince of Persia on the GameCube (I think? It was a long time ago!) had a mechanism very like this, where you manually rewound time after you died/failed. More Action/Adventure than an RPG, though.
