Are you bringing out the great myth for Halloween?
On a mobile, the tank is made of composite, lighter and with behavior without fragmentation in the event of an impact.
The danger is only an overpressure, with release of cold.
Firefighters go into burning buildings with a 300 bar bottle on their backs ...
With a battery, you have both overpressure
et combustion.
And with a gasoline car, aren't you afraid of it? I saw a space burn on the ring road, nothing was left in less than 2 minutes, and I'm not even talking about a gasoline truck stuck in a traffic jam on the ring road ...

You're only talking about volume compression, and the usual technologies, for which energy efficiency is the least of the concerns.
There is a huge field of optimization, since it is possible to achieve 90% efficiency:

impassable !
And if you compress at home, the heat is recovered in the room thus heated, it is no longer a loss.

On the contrary, it is an advantage, it means that the engine uses ambient thermal energy, thus putting the theoretical limit of the engine energy efficiency at 230% for the Airpod engine ...
And you can cool the vehicle in summer.

There is no particular difficulty, the 200 or 300 bars, it is well known for diving or firefighters.
As for autonomy, how would it be disappointing?
