It’s cost effective when you take the same amount of cars off the road and factor in what those cars would have contributed to

• road maintenance
• road congestion (mental health)
• environment

They are very common where I live. They are designed so that people can sit there if no bike is using the space. And usually they are bikes. Still not enough space for a cargo bike, but more than enough for a normal one.

That seems a classic chicken-and-egg issue. There is no room for cargo bikes because it’s not cost effective. That means people can’t easily take their children and stuff anywhere except with a car. Because everybody uses the car, the train cars are not cost effective.
