>I would not trust an automatic robot arm For 95% of newish cars this problem is fairly trivial because the gas cap/fuel doors are so similar (there are exceptions, I'm specifically thinking of cars that require you to press a button inside the car to open the refueling port), and any college robotics lab could design a system to handle it that was much less likely to scratch your car/spill gas than a human operator. The problem is that in Oregon/New Jersey it's a jobs program, so regulators are unlikely to allow something like that. In every other state, gas stations have no incentive to pay for such a system because they have no labor costs to save.
