There's the same situation in Europe too. One option is to build large car parks on the outskirts of cities close to the highways and with good access to public transport. This way people living outside the city center can still use their cars to get to the city, but can bike/escooter/walk or take the subway/bus/tram to get to work. Even in Marseille, a city with terrible public transport, there are some of these, with new ones in construction or planning stages. Parking is free or heavily discounted if you have a transit pass. I believe this could work well in major US cities with a dense downtown area.
