> The company has engineered its own gas delivery trucks with a proprietary system, called the Fuel Vault, which allows Yoshi to access any car’s tank, even if the gas flap is locked

I'd like to know what a glamorized fuel cell has to do with somehow circumventing the lock on many gas caps.

I imagine it's some sort of tool that somehow defeats the locks on such gas caps and flaps, which poses interesting questions about legality (as they acknowledge in the post). I certainly would not signup for a service that risks breaking or damaging my vehicle, nor am I about to hand over keys to my vehicle either.

How large of a market is there for this really? Frankly, is this a problem really needing solving? This company must charge a premium for the service, which makes your fillups cost more than if you just spent the 2 minutes it takes to pump your own gas.
