People with kids will still want to drive. The falling birth rates are reducing private car ownership in cities already.

Sure, but people with kids already use their cars more efficiently: more trips per day + higher vehicle occupancy.
If you can replace 1 million, single person vehicle, 2 trips per day (work commute) with cheap ubers or robotaxis... that goes a long way to reducing congestion.
Of course I'm talking about voluntary reduction by offering cheaper, better alternatives. Don't think I'm in the 15-min city, surveillance heavy, agenda 2030 camp 😉
