My point is that it's not a good idea to expand bike lanes in big city centers where you already have public transport, especially not in places that doesn't have a bike friendly climate. It's simply not a good use of the space, can't really make any good case for it except some people think it's fun, which is extremely weak. And I don't understand why it makes cities such as Amsterdam and Copenhagen so much better, people just get randomly happy from the joys of riding a bike, or what? I'd rather have many more practical solutions with tangible results such as actually reducing the time and energy we spend on commuting, not increasing it.
I don't know what is your background, but many cities are doing it and it's not only about enabling bikes but also to disable passenger cars, and the main reason is it makes the places more livable and enjoyable: it's quieter, the air is cleaner, the streets are safer, people actually spend more time outside. So this is a practical solution to a problem people have: noise, pollution, loss of public space to car infrastructure.
