I thought the same as you too when I was 23. I live in Singapore that has very accessible cheap public transport. But I still got a driving license and I'm so glad I did. Two words: ROAD TRIPS.
Some places and things are impossible with public transport. Driving from Calgary to Victoria Island in Canada, driving from Melbourne to Sydney. Stopping by to get some food. Check out nice mountains, coasts. It's not so much about the car itself, but the life skill to get in a car and your AOE (to borrow a gaming term) extends to several kilometres with unparalleled flexibility, except for big crowded, car-less cities.
It is being able to get in a car with a group of friends and you're golden to have a fun time out. It's about an emergency and you have the skill with you. It's about another option if where you live has car sharing services and you need to pick up something from IKEA. Cars are one of the most perfected piece of technology humans have came up with, almost to the point that it is an extension of us now.
What the fuck bidets are not common in the West? Scared that it will spray poop bits in vagina??? What's going on over there.
