How do metal boxes cost $50k each?

Investing in helping diversify anything infrastructure related in a city of that size is always going to have a positive return on investment. The best example was snow shoveling, when people can go to work, they can participate in the economy and pay taxes. With this, people will more readily ride bikes for routes that are slightly too long to walk, reducing car traffic, speeding it up at the same time while reducing wear and tear on the street surface and ecological impact which comes with it's own price tag.

I think it's the motors and airbags.

Because there's 50 people involved and everyone wants to do maximum effort to cover their own ass.

It's good to see this decade long slog coming to fruition, but it is still a dog house for a bike, not exactly inspiring infrastructure. Painting them anything but slate grey would probably help with visual appeal, so here's hoping for that.

Thinking of the top of the mountain, the Netherlands builds underground bike storage roughly the same as these bike sheds, on a per bike basis. Of course that type of permanent infrastructure is time consuming to construct, but this sudo permanent shed rollout is spread across the next five years, so not exactly quick.

a mix of smaller secure lockers in residential areas and larger high-capacity facilities in commercial areas and near transit hubs

Yeah, it's a combination of racks, lockers and sheds!

How much to live in one?
