"Understand and accommodate" can cover a much broader and more ambitious range of actions than that. Look at the plain words. What I'm saying is that we should understand why people have made the decisions they have, what capabilities or benefits they expect, and trying to preserve those capabilities or benefits even if it's with a completely different kind of infrastructure. It's just basic requirements analysis.
You know what's truly silly, since you used the word? Ignoring others' knowledge, judgment, and agency. Pretending those things don't exist. "You're a dummy who has been duped, screw your feelings, ban cars tomorrow" is both un-empathetic and absolutely useless as a way to formulate policy, but I see it again and again and again from the extremists in these discussions.
Not sure if it's what you meant, but that phrasing reverses cause and effect. The arrangement of homes, offices, and retail precedes most individual housing choices. In other words, people chose to live in places, already knowing what the transport implications would be. They weren't yanked out of their car-free utopia and forced to live a car-centric lifestyle.
I agree that the car-centric way we do transit and urban planning is absolutely disastrous and needs to change, but part of making that happen is not simply dismissing people's revealed preferences as something imposed from above. It's the solution that's likely to be imposed from above, and I'm OK with that personally, but in the political real world it pits a whole bunch of noble principles against the hyper-individualist anti-government attitudes prevalent especially in the US. That's how you end up with "ban all cars" on one side and "rolling coal" on the other. The trick is to understand and accommodate the reasons why people choose to live as they do, while still moving toward a better future.
