From a refinery? Losing car dependency doesn’t mean that the global oil industry goes away over night. Shoot, if we invented completely safe and cheap scifi teleporters, making all current forms of transportation obsolete, I don’t believe every factory in the world would stop producing gasoline.

My thinking for this primarily comes from vacuum tubes. The technology has been completely replaced by better performing, cheaper, smaller, and more reliable components for about 50 years now. However, there are still 2 or 3 factories churning out tubes for guitar amplifiers supplying the world for the handful of enthusiasts who enjoy that sort of thing.

Go ahead and throw mechanical typewriters into that same category of “Wow! I can’t believe that they still make these?” as well.
