Although, these stats are people who would consider giving up cars, among those who currently own one.
People who don't need a car and already don't have one won't appear in these figures
If you imagine the perfect fictional country, then for that country the bar chart should theoretically be at 0% - because that would mean everyone who doesn't need a car doesn't have one, and anyone who does own a car needs it very strictly for jobs only a car can do, no matter how good the transport infrastructure and planning and zoning are.
Me too, but it's the percentage of those who currently own a car. I guess, in NL the percentage of people who own a car is less than e.g. in Germany.
I'm also surprised that the share in the US is quite high.
