> Well, the business model is hard to get right. It's faster than plane and car on medium distances, but capital costs are enormous compared to either. Consider the climate impact costs. Part of the problem is that airlines and car owners externalize a significant cost, making those modes of transportation seem relatively less expensive. In reality, everyone else covers those costs.
