Very few advocate for the total elimination of cars, just that they are very, very overrepresented in terms of amount of infrastructure built and city design. The argument isn’t to take cars off the table, but that they shouldn’t be be the default option, and therefore that cities shouldn’t be built assuming that most will have and use one. Because when you build assuming their use, you tend to create a place that requires them, and makes life very difficult for anyone that cannot or will not use one.
