I like that idea too. But I don't like the idea of forcing a human to do the work. I like the idea of legislating for standardized interfaces between gas pumps and gas doors on cars, such that it becomes possible to build "full service" robot gas stations.
I think the only reason this hasn't been pushed for, is that the automotive-sector companies with the robotics expertise are all electric-car companies. (Or hydrogen-fuel-cell car companies — lotta robotics people in that space.)
About once a year or so, I get a person at the pump behind me that is FURIOUS that I am pumping my own fuel, and start yelling at me. They ignore what I say, until the station employees confirm with them that yes, it is legal to pump your own Diesel in Oregon, just not gasoline, since gasoline is flambile. (the existing law is governed by the state fire marshall). They are usually grateful, since they are always down at least one attendent, and busy as heck.
If this were true, then there would be gas stations with attendants in the other 48 states.
That may have been one excuse, but as a long time Oregonian my recollection is that the real reason is voters have rejected it when it did come up for a vote. People liked the idea of citing in their car and letting someone else do the work.
> They intentionally kept the gas tax lower in the state so consumers didn't notice the price difference
I recall once reading that the cost of insurance on a self-service station isn't far off the cost of staff, and it's mostly a wash overall.
> waiting for the "service" could sometimes be longer than the fill-up itself.
These days, Costco runs a massively efficient assembly line fill-up procedure, and self-service might well be slower. At quieter stations that may not be true. Even then, it depends on if you can navigate around the cars that are just parked in front of a pump while they are shopping inside the convenience store.
