Easy there, we do ~15000 km/year, but ~4000 of those are on long trips. That’s “a significant fraction”. I didn’t say I spend all day every day in the car.

There are many logistical reasons why we still need one car, but we are actually also able to walk, bike, and use transit.

And I expect I spend more time on a train that you do. But it’s not always the most practical option.

Crossing the alps on a train means too many changes, with trains from different companies, and my bored kids (depends on the origin and destination, but it’s true in my case). Even using the plane, with all the associated changes and buffer times, usually takes 6 or 7 hours.

Holidays in the mountains also gets a hell of a lot harder without a car. That’s true in general, but it’s doubly so in the places where I like to go (less crowded secondary destinations). Public transport requires density, and the last thing I want in the mountains is high density.

Edit:

As I wrote in another message, I would have thought that:

“Reducing car use is better than just replacing them. Cars cover a lot of difficult corner cases, but let’s offer good alternatives for the day to day life”

should be a pretty uncontroversial take, and yet I’m here discussing with people that want to use cars everyday, and cover the exceptions with the alternatives.
