No one said it is, and I even clarified at the end that better public transport infra makes life for drivers easier as well. More public transport means less people on the road since they're concentrated in buses and trains and trams, meaning for people who do need cars, they have to compete for less space on the road.

For example the Netherlands simulatenously has world class public transport infra and the happiest and most satisfied drivers. 60% of the country still drives, it's just that it's not the only option and the drivers also take public transport and bike when it's more convenient than driving.

The point is that good public transport makes cars unnecessary for the vast majority of everyday life in an urban setting. And, in particular, it means that taking away someone's license, even for a long period of time, doesn't have to be as crippling as it is in cities that don't have good infrastructure - hopefully leading to society being way more willing to apply drastic driving penalties to repeat offenders.
