If the driver does not respond within a predefined time or if a failure occurs in the system, the system needs to do a safety stop in ego lane

Tesla's system doesn't do that. If the driver doesn't respond, the car can crash. That's why you're required to pay constant attention and have hands on wheel.

Read a book about Bayesian statistics (co-author of the Economist model, Andrew Gelman, has written perhaps the most notable one but it's not a light reading).

How can you compete on price with 320 km/h trains? Hyperloop One seems similar to Maglevs (which are already too expensive), except it has much lower bandwidth, requires straighter lines due to the higher speed, has more serious thermal expansion issues, worse connectivity to existing transportation networks and of course there are safety issues, adding to the costs.

The advantages are speed (people willing to pay more) and maybe operating costs.

I just can't imagine the economy working out, although I hope I'm wrong. How confident are you it makes economic sense, is it more of "we've made a proper analysis, and there's a decent chance there will be market for it" or "this is a research project, we don't have exact plans for dealing with thermal expansion and safety, but let's hope it works out".
