The answer is so simple. We really really really really like our cars/trucks/SUVs in the US and have agreed that about 30,000 to 40,000 people a year will die so that we can keep driving the way we do. It’s the price we pay for the way we choose to live.
I like how your comment is downvoted even though this hypothesis is directly supported by the data from the article. Fat cars getting fatter, pedestrian-hostile streets becoming faster, city infrastructure requiring people to drive everywhere. Hmmmm, what could be the reason.
I really really really disagree with this.
A huge number of people could design a car-free or less car dependent life for themselves if that was something they valued highly.
People just don't value it as highly as they claim they do.
