My thoughts?
It wouldn't be practical or economic in UK.
To reach its proposed cruise speed it would need to fly in controlled airspace, i.e. on airways and would therefore usually need to operate on slot times.
So it may as well operate from an airport. In which case it will get the benefit of the runway (and would in fact probably be restricted to use of the runway, as helicopter movements often are).
In which case the vertical takeoff capability would be unnecessary and go to waste.
So it would be uneconomic to buy or operate and most folk would not buy one and would simply opt for a bizjet instead.
Unfortunately, hybrid vehicles seldom work better than a more thoroughbred type.
I'll bet this one is stillborn, like many before it.
