I recall a debate early on that one of the hurdles to Hyperloop viability was obtaining right-of-way within city limits. Getting to the outskirts was seen as probably doable since obtaining right of way involves relatively large parcels and a fair whack of government owned land (i.e. freeways). But in a city, there would be too many players to satisfy and the ends of the line would not be able to get close the the center of the cities, greatly reducing the value of the system. Tunneling within city limits may resolve that.
