If most of the service station you past sell diesel, you will have a hard time convincing anyone that it isn’t readily available.
A service station having additional pumps of gasoline does not make the diesel less available.
Did you see any long lines waiting to get to the diesel pumps while the gasoline pumps did not have the lines?
Do you really consider waiting behind a car or two to get the diesel pump make it not readily available?
32 pumps at 3 stations between my work and my gym all selling gas.
4 of those pumps at 2 of those stations selling diesel.
That’s the difference between readily available and limited availability.
I don’t see long lines for diesel because if there was enough demand to make long lines they’d put it in more pumps. Like I said, that’s the circle, people don’t buy diesel vehicles because it’s not readily available, and it’s not readily available because people don’t own enough diesel vehicles to create demand. What I do see though is that the 2 pumps at a station that have diesel tend to be the most convenient corners for entry and exit, which makes them the most popular pumps, which makes them the most often occupied. My “favorite” station (until Chevron sold it) was a 16 pumper with 2 diesel on opposite corners, I almost never got gas at the diesel pumps because they were always occupied, I’d swing into the middle pumps where there were always one or two empty. And yes sometimes there’d be a car waiting in line at the diesel pumps.
Having to wait in line because it’s only at 2 pumps while gas burners have their selection of a dozen unoccupied pumps is limited availability, by the very definition of the words. See there is a limited number of pumps available, pretty easy stuff.
