People who are commenting that they are single and don't drive and get about just fine, I am sure you do.
But in a couple, which is the scenario in question, when one drives and one doesn't, the non-driving person is going to ask the driver for lifts, or use the fact that their partner drives, for convenience. And even if they don't 'ask' the driving partner would have to be a total arsehole and want to inconvenience their whole family to not drive in these circumstances.
Family holiday to the cotwolds - 'how shall we get there?' 'oh well I drove us on the last holiday, so this year, we shall all get 2 buses and a train with our suit cases'. Not gonna happen OR
Kids need picking up from swimming 'OK, well I picked them up last time, so now its your turn, you can get a taxi for £20 instead'. Not gonna happen.
The driver is always responsible. And that is why people who drive often would prefer not to be with someone who has chosen not to drive
Travelling home from my last holiday involved eleven different trains, plus walking between Birmingham Moor Street and New Street, and a sprint down four flights of stairs in Berlin Hauptbahnhof. It was part of the fun. Much better than struggling to stay awake at the wheel when driving for a 4am flight.
I owned a car at the time and used it to get to/from the station. On my return the battery was flat (battery needed replacing and the car had been parked for ten days in January) so I had to call recovery. These days I'd jump on a bus to the station if I had more luggage than I could carry on my bike. The bus runs every 20 minutes from 0600-2300ish so that covers all bar the earliest and latest trains. If I really needed to take a large bag on a very early/late train, I could walk or take a taxi.
Swimming? That isn't difficult, for most of the population buses will do for journeys of more than a few miles. For shorter journeys: "Right kids, get your bags and put your bike helmets on, it's time to leave for swimming".
If I want to see a concert/opera? Plenty on offer in the nearest town (only a couple of miles away) and I often get the train to Liverpool/Manchester/London/Europe. Pubs? There's two in the village, plus plenty of restaurants in nearby towns. Walking/cycling home means that I can have a drink too.
When a relationship/kids come along, I see little need to get a car. I'd be quite content being a no-car family.
I can see why this country has such a problem with obesity. I can also see why the world has such a problem with emissions.
