Getting your drivers license is also very costly, must be transferred when you move country, in countries like Sweden (where I live) you have to retake your test every 10 years.
It also requires a lot of time to do anything with it. It's an administrative document, like a passport. You can say "getting a passport is important" and I'd believe you, but better to get it when you need it rather than pre-emptively, because otherwise you're wasting valid years.
I find often that when we do things like taking a drivers license we feel like we are incentivised to use it, when we use it we purchase vehicles and register them and then we have sort of a sunk cost feeling. Once you've invested all that time and cost using it feels cheap so you are more likely to use it.
On the flip side, because I don't have a license I make subtle decisions to avoid using a car, so my life is relatively car-free, on the very rare occasions I do need a car I can hire someone and it works out significantly cheaper in the long run.
