Forget gas: This type behavior is a waste of time! The most precious resource of all.
I don't like planning, and I forget things. So I sometimes leave the light on when I leave the house, forget something when I have to do groceries at the store so I have to go back, if I have half a meal left, I throw it out rather than freezing it, etcetera.
I've learned that, for me, accepting that gives me more peace of mind than trying to plan every part of my life. It also wastes less time than being super organised with my groceries, and I also end up throwing out less if I just shop for a single meal at the time.
Still, my spending is not that high, and my ecological footprint is not big. I switch electricity companies each year, taking advantage of their sign-up bonus. I make sure to double check that I've turned of the heating when I leave the house. I only have LED-lights in my house. I invested in solar panels, which will take a long time to earn back. I bought a house that is 20% cheaper than what I could afford. When buying the house, important factors were that it was well isolated, and that my commute is short, cheap and fast (20 minutes by bus). I compromised on its garden and square footage. I buy a phone that's 300 euro rather than 700 euro and use it until it breaks.
To me, 'don't be wasteful' is best applied selectively, both ecologically and economically. I approach it like an optimization problem: Identify the bottlenecks and attack those.
Edit: Because it is essentially celebrating the fact that you are at least in part measurably dysfunctional. It's part of the zeitgeist, but there is such a thing as taking it too far.
Throwing things away is so difficult these days that I try to make purchases that avoid it. But like...we still have my 5 year olds car seat in our garage because no place will take them (I have to make a trip to the dump, or get a junk hauler to come by with a big load for them and a few hundred bucks).
Our garbage system allows us two "bulky item" pickups per year with our regular garbage if we call in advance where they'll take anything in a 3x3x6 volume.
For everything else, I just destroy it with old power tools.
The 1980s are funny, because, the early 1980s were one of the periods of highest sustained gas prices in history, while the late 1980s and 1990s are the lowest ever.
This is most likely caused by those oil shocks.
If anything, our family culture of thrift came from parents who were small children during WWII rationing and grandparents who were children in the Great Depression. I sometimes can even imagine there is an epigenetic factor here, leading to more obsessive (compulsive?) planning, optimizing, and risk management behaviors...
Also, I don’t think people would want to waste all that time making 12 trips a day whether they care about the price of gas or not.

This seems like a bit of a straw man. I live in a pretty suburban area and drive my car probably 2-3 time a week. I've rarely seen my neighbors, even the ones with a bunch of kids drive more than 2 or 3 times a day.
If you've known people that "make 12 trips a day" they might be a very rare anomaly, I don't think this is normal behavior from what I observe.
a toy with optional batteries obviously requires less battery use than a thing which requires a battery. it's tautological.
While I'm on my 4th trip out for the day I'll bet he's already back home watching TV.
Joking aside, I've definitely see the cost/hr add up by purchasing new things that still have bugs to work out. The price might be $500, but I'll spend another $700 of time working on issues. I'm fine being a few months late to the party so I can conserve time for more important things.
In the words of the characterized OP: "If it ain't broke, don't fix it"
I can't fucking wait to retire, and spend time doing what I actually want to instead of useless work.
So unlike so many people today, I don't make 12 trips a day to stores/friends/whatever when I can just make one or two if I actually think 5 minutes ahead. That applies whether gas is $1 or $5 per gallon.
I also try to make good use of what I own and not discard things that are functional simply to get the new shiny.
