There are so many failure cases, and most people that regularly pump their own gas are naive/blase about them. (Watching people at gas stations fill gas tanks while understanding that massive list of safety requirements, being very aware that all mistakes involve an explosive substance, and counting all the violations you can spot is one "fun" way to lose a lot of faith in humanity.)
Thankfully, there's a lot of regularly inspected safety equipment compensating for how blase so many people are. Modern pumps have all sorts of auto-shut-off sensors and require all sorts of (literal) firewalls and conscious designs. These have mostly eliminated a lot of the errors from being fatal in practice, allowing so many of naive and/or blase to live another day.
In practice in places like Oregon (and Japan) this was a jobs protection thing. It saved some low wage jobs from companies that had every incentive to eliminate those jobs to scrimp and save money. It was more useful to Oregon to keep those jobs than to let them disappear.
(Arguably Oregon is allowing them to disappear only just a few years in advance of them disappearing naturally because gas pumps are likely to start disappearing altogether as EVs become more prominent. They can't protect those jobs in the EV present.)
EVs were originally a "Woman's Car" because a petrol car would get the operator quite dirty while an EV wouldn't stain a dress.
There is no way gas stations on highways are going to close down in the next decade. But if your highway wasn't popular enough to currently have service stations at their rest areas then I don't have much hope your gas stations outside those areas.
Of course this does mean that you might have to drive ~40mins roundtrip to fillup your gas.
You can pump your own diesel, or your own gas for a motorcycle. But it was for Class 1 (I forget number) flammable liquids
