Two things make your objection less relevant.<p>First, Amsterdam had similar problems to the US in the post-war era until the 1970s. That is, the cities were being rebuilt for cars, bicycling infrastructure became worse, and traffic deaths rose. The city had to be re-engineered to get where it is now. See <a href="https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?t=3&amp;v=XuBdf9jYj7o" rel="nofollow">https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?t=3&amp;v=XuBdf9jYj7o</a> for a video.<p>Second, and concerning topology, look to Trondheim, Norway as an example of a bike-friendly city with hills. And from what I&#x27;ve read, Portland, Oregon is also pretty bike friendly, with similar topology to Seattle. So, why can&#x27;t Seattle be more like Portland in this respect?
