Some of that is solved by dramatically increasing density, though. Nobody enjoys long commutes and a lot of people who currently drive probably wouldn't drive if they didn't have to, so presumably with enough added high density housing and public transport capacity traffic could be curbed considerably. Rideshare services are a big factor too, but that could be resolved by enforcing a cap on the number of rideshare vehicles in the city.
