They're an American site, of course they want to reduce the use of cars, cars have been hideously overpromoted in the US, resulting in insane costs for the user, crazy high costs for the government, horrible health impacts, high fatality rates, tons of unnecessary pollution, etc.
In most parts of the country, the car is literally the only viable way to make most trips. That's how much they've dominated every aspect of our transportation system.
Taking the 'position' that such a monoculture is bad, is about as political as asserting that lack of racial or gender diversity in workplaces is bad.
Do you feel bothered by sites that don't argue the other side too, that we should keep homogeneous workplaces around? Does it count as a pro-diversity 'bias' when they don't do that?
> the idea of ending cars is ridiculous
So wait, did you accuse me of not reading them because you haven't read them yourself? You see, they've never actually promoted this, and yet here you are, asserting that they have.
Reducing the use of cars in favor of other, less harmful modes sure, and car bans in some select areas, yeah. You can't walk on the freeway usually either. It's the height of absurdity to equivocate that with a total ban, anymore than saying that people who don't want me biking on the interstate don't want me biking anywhere ever.
