I think GP is trying to say there should be some sort of physical barrier (plastic posts, or potted plants or anything) to prevent the cars from crossing the line. Even we're serious about keeping cars out of bicycle lanes, there should be a physical barrier separating cars from bicycle lanes.
There are multiple TikTok accounts of (I think Canadian) bicycle parkin officers doing just this.
They basically just drive on bike lanes and give people fines for parking on it all day. People are just lazy, there might be a parking space just across the street, but they'll still rather park half way on the bike lane and half way on the pavement.
