This is a very different problem than actual efficiency when mowing a lawn or vacuuming a rub. Turning takes more work and time, and you miss a part of the 'square' when you are turning (the arc of the curve is not a straight line). In addition, vacuums especially have an area at the edge of the machine that is not cleaned as well, which is why you want a bit of overlap in your lines.
Plus, when mowing a lawn, you often want to leave a nice pattern, so you cant just go for pure efficiency.

Plus mowing a lawn is meditative
Copying another comment I made earlier
When I was laid off a couple months ago, the first thing I did was go out and mow my lawn. One hour of simple, clean labor, with clear progress, goals, and solitude. It helped me stay out of a bad mental frame, and when I finished I went inside and sent out a few hundred applications
Over the next several weeks, I spent a lot of time that wasn't spent on finding a new job working on my yard. Fixing sprinklers, cleaning up the edges of the grass, turning, peating, and mulching garden beds, and more
While this job search period took longer than any of my past ones, and ostensibly should have been more stressful, it wasn't. Is that because I spent most of the downtime working outdoors? Probably, who knows? It was certainly a better use of my time than sitting indoors moping

That’s rather cruel. Optimizing lawn mowing conserves human and machine fuel/battery, especially on large plots or as professionals or in hot climates. Misapplying optimizations to one’s free time is absolutely in line with your stereotype, but that’s much more a widespread defect of judgment in computer engineers than in mowers.

It's a cute little optimization puzzle they made for people to solve, with lawn mowing as a graphical hook to make the problem more approachable and fun.

How is this any more or less valid a use of time vs. mini-golf?

This can heavily be mitigated through technique. If you walk straight and just turn? Yeah, the corner is missed. If you explicitly come to a stop and do your best to do a full 90-degree turn before moving? The only curve there is going to come from the shape of the blade, and is almost guaranteed to be a tighter curve than just walking and turning without stopping.
Yes, it takes longer. But if it's worth doing, it's worth doing right, even if it takes twice as long, no?

Semi-related: Worked as a landscaper during my youth, one of my first jobs
I used to think that the line patterns mowed into grass were a purely aesthetic thing.
It turns out, the lines are mowed in a rotation to prevent wearing out the grass and causing damage. First you mow length-wise, then width-wise, then diagonally, finally diagonally in the opposite direction, before cycling through again.
Useless information for you today.
SoftTalker 55 minutes ago [-]
I don't usually do the diagonal paths but I do try to go at right angles to the previous mowing each time I mow the lawn (excepting when I can't remember which way I did it last time, but it's usually still visible) or a few narrow areas which really only make sense to mow in one direction.
deweywsu 1 hours ago [-]
Absolutely correct. If you always mow in the same direction, the grass always gets pushed in the same way by the lawnmowers blades and it will eventually morph to that direction and lose strength, which appears as grass that doesn't stand straight up, and it looks worse.

I believe the point is the wheel lines and to vary where the wheels go by changing the pattern each time you mow so you don't, for example, always drive exactly down the fence and cause a rut or mulch buildup or missed area.

We people vary frequency with weather. Lawn tractors are heavy and, due to moisture, ground isn't always hard. On large properties some of the ground stays moist longer due to drainage issues. So yes, after years of indifferent mowing, one can detect where wheels have been moving topsoil.

When I used to mow neighbor's yards as a kid, I'd do a crosshatch pattern that I'd rotate 45deg each week, orthagonal vs diagonal. Just doing one direction looks fine but a crosshatch looks even better, especially if they have thick, healthy grass. I wouldn't be as meticulous on the side and backyards, those would just get a single, slightly overlapping pass in whatever direction was convenient unless they had a really nice backyard, then I'd do extra there.

I started doing it and immediately felt like I was optimizing for minimal moves like a video game, rather than what I'd actually do which is not the same strategy. There's a handful of things different
- The direction you mow leaves a pattern that I generally try to stay parallel to, and mow alongside, and go for long strips even if I have to do a bit of running over already-mowed parts
- I may go diagonal at times
- I've never had a yard that's a maze of rocks
- If there's a small patch I need to mow around, like a garden, I'll likely do a circle around that and use the edge of that mow line as a new edge

I'm right with you. My dad was a farmer and taught me: First deal with the irregular, annoying parts on the outside. Create rectangles with a long side and turning space on each shorter side.

Hence why I went for the irregular strange part on the lower left first, and then the more regular part on the right. That's the weird rain collection, herb garden, thing we have at the back.

Though I solved it in 49 moves (yay me), I realized when thinking about efficiency, it didn't take into consideration two important things:
1) all of the turns I was making in order to be most efficient, whereas overlapping a few times would have probably taken less time, and
2) I spent a lot of thinking on the spot, as to what was the most efficient path, rather than moving the mower.. so while I only took 49 moves, the time spent on inaction may have balanced the scales with someone who just kept moving.
There's a life lesson in there somewhere, I'm sure!

In addition to the obvious things already mentioned, the authors miss a subtle but important point.

For others it might be driving long roads, or doing chores inside the house, cycling, and such. Otherwise, it’s inefficient and useless, the lawn can be replaced with better flowers or even small garden, or simply pave it and save the time and efforts and electricity/water doing a repetitive thing like it, and also spare your neighbors the noise 7am Saturday morning, and if you look at the bigger picture, the process is a total waste, you waste water to grow crops only to waste electricity to mow it later, it provides no useful product or outcome either, no flowers, no food, not even cosmetics like fancy looking garden, plus the maintenance and/or initial installations.

no comment on the results or the premise of are people good at mowing or just good at playing "snake"
i would be very curious to see if this same result held up when you also factor things like turn effort or "prioritize the longest straight lines bc they look cool"
In the nude.
Mowing a lawn is about creating straight even lines not optimal routes.
If somebody reports it, the city can and will come tear it out and charge me for the work.
"Ownership" is a funny thing.
Is there supposed to be more content than this?
... If JavaScript is required to view more content than this, why?
By "asked people to mow it" they're talking about the visitors to the site. It's interactive.
It's somewhat a mistake not to have "skip to results" in the actual html. On the other hand, it makes sense they want to force people to see the landing page first. And unless they want to add a whole rendered fallback the results page isn't going to be super functional without javascript.
The noscript version needs a button and a big box with an X. And even then the button would only be half-functional so I understand skipping it. It mostly just needs a "missing content" warning.
