China has almost 400,000 electric busses.

How are those working?

You tell me. Just saying there are 400,000 doesn't speak to their quality or reliability.

If you have 400,000, you might care less about reliability.

If there is always another spare, a few breakdowns each day don't matter as much as they do in a smaller fleet.
