Howzat work with a locking gas tank? And I played it without sound, so maybe they said - but I didn't see any indication of anyone paying for the gas. And what if you only want $10?

Is this really a solution to a problem that doesn't exist? Most places you get gas now, you pump it yourself. If you want to pay more, you go to one of the few full-serve stations where a minimum wage pump-jockey fills your tank for you. You could pay that guy's wages for a long tmie for what this robot must cost.

Not to mention, there's going to be a lot of people leery about allowing some machine to maneuver a metal nozzle near their paint. Or wonder whether the machine will miss their tank and pump 40 gallons onto the ground.
