There is likely to be modal filters that make it practically impossible for through traffic to use these roads effectively, and if actually just people with a destination in the concerned area drive into it because for everyone else it’s just a winding detour, it’s likely very good for traffic in the area. Seeing the bike infra progress in Paris over the last few years I do have some optimism that modal filters could be going up soon if they are committed to get rid of through traffic.
