Who did they survey? The rich people living in the center of Amsterdam that can afford to not own a car? Or the poor people living in Purmerend that now have a worse commute than before?
Of course the people living in Amsterdam will answer the survey positively. It's not those people that are impacted. It's the poor person working at IKEA that now has an extra 30 minutes of commute because they imposed parking restrictions near their job. The rich Amsterdam city center person shopping at IKEA can take the metro because they can afford to live such a lifestyle.
