...I suppose that non-drivers will never really know just how useful a skill it is, and how new opportunities are available to people who can drive.
People with a driving licence can still chose to go by train, use buses, cycle and walk places. We do! But people who have never learnt to drive, dont have that choice.
Getting from South West London to Dulwich, to visit the Horniman museum, for example, would be quite exhausting on public transport, for a day out with the kids. I know how to get there by train, that is not the point, getting any where from SW london requires a combination of buses, trains, tube, walking, I have not unlearnt this particular navigating and planning skill just because I also know how to get there by car!
I can chose whether to drive into Oxford street, do my shopping, in the knowledge I can drop anything I want into the car, without going around central London laden with bags. I can take a bus to a different end of London, have lunch with a friend, or to a park for a picnic, and then go back to my car. I can decide not to go home, but visit a friend in North London for a meal, before driving back in the evening, kids falling asleep in the car, after nipping into Ikea. I can cram a whole lot into a day in Central London, if I have a car, and it is easy, because I can drive, I can navigate. I also know how to do all this by public transport.
It makes my life easier, it means I have options. On friday evening, we might decide to go to New Forest the following day. We pack our car, put the bikes on the bike rack, and can be off by 7 am, and be on our bikes by 11 for a fantastic cycle ride. No need to check our luggage into a b&b first, it stays in the car, and we just get our stuff when we are done cycling, after driving to a nice country pub for dinner, we can settle at our B&B for the night, ready for another day of outdoors adventure before heading back.
I would not be without a car. There is much more I can do WITH a car, than without one.
I dont think anybody can really say "Now that I know how to drive, and I have a car, I have much fewer options available to me in life".
The difference lay in the CHOICE. And I prefer to have choices than not.
