Trains (etc) require a lot of infrastructure, especially if you've forgotten to plan for them for a century or so.
In Australia, the Sydney - Canberra - Melbourne route would be a potentially interesting one for this, as road travel averages 100km/hr, but has obvious downsides. These are short leg trips, though I don't expect this tech would alleviate most of the land-based delays, and (traditional) incumbents would not be happy if they did.
Either way, a less painful than jet, cheaper than jet, (slightly) faster than car, less attention demanding than car, travel option would certainly be relevant to quite a few people's interests around the world.
That kinda only makes sense if you define "everywhere" as "everywhere people currently want to go".
There are _huge_ swathes of Australia that probably don't have a single passable road within 100km. Once you get much more that a couple of hundred km from the coast, Australia is effectively empty. Any population is way down in measurement noise.
Not to mention safer than a car or jet. Airships are quite safe, contrary to what people think after what happened to the Hindenburg. I wonder how this hibrid airship behaves in high winds.
They aren't unsafe but hybrid airships with the current air passenger transport procedures in place could be even safer. If a HAV goes down with 150 kmh speed and 60% buoyancy there's a better chance the passengers would survive provided there is no pressure loss.
