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

> you often want to leave a nice pattern

Even when it comes to mowing, different people have different goals. I live out in the country, and tall grass means bugs and ticks, so my mowing tries to strike a balance of short grass near the home and the property edges to stop the ticks, medium grass most everything else because we like to let the clover grow, and tall grass, un-mowed for years on some spots, to allow an ecosystem where we still get monarchs and nightly fireflies.

Totally understandable if suburban folk have different goals, but either way, 100% agreed that efficiency is a secondary goal at best.

This is mentioned in the article when discussing a player that found the optimum route:

> Sarah also did something that appeared a bit unnatural. Instead of simply continuing straight a few times, she intuitively and preemptively turned in a snake-like pattern. This highlighted a key difference between real-life mowing and our simplified game, an approach that strong mowers exploited. Sarah, an avid gamer, seemed to recognize this strategy immediately.

You should see how optimal the poster's first dates are! Meet at a location with premade bottles of Soylent while they ask 15 questions. Done in 30min. Optimized away the cost and time "wasted" at restaurants or mini-golf type activities.

I was thinking the same thing. When actually mowing a lawn (or similarly, vacuuming a carpet/rug) I tend to optimize for either long lines or rectangular sections where I can easily mow a straight pattern.

Why not mow in a spiral then hit the 4 corners last?

The lines change mowing so much!

> and you miss a part of the 'square' when you are turning (the arc of the curve is not a straight line)

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?
