I admittedly only have been in Seattle once, but it didn't feel very friendly for people without cars (I don't drive myself, and it was a pain). It's better than average, but average is not a very high bar.
Is it really a minority of people who have cars there? Even in NYC, while a lot of people don't have cars, I'm not sure it's the minority.
Regardless of all that, if you build up without car infrastructure, you need to up public transportation to keep up. If you do then there's no problem. Is that happening in Seattle? In Boston/Cambridge people are also asking for parking minimums to be done with, but the public transportation infrastructure is getting worse and worse, so you have areas like around Cambridge's Alewife that are becoming massive traffic bottlenecks as they're building up around it. That's just not scalable.
In 2014 an Oregon live article claimed 17 percent of Seattlites didn't have a car. So no car owners are not the minority, despite what the op wants you to believe. Yes in the three years since that article had been published in sure more people have given up cars, but they are still in the minority. Given how poor public transportation is it will be a while yet before car owners are in the minority
