A Driver Predicted a Kid Would Dash Out From the Park. One Did.

One driver's textbook 'defensive driving' instinct gets put to the test in real time, and the replies fill up with near-misses of their own.

What's going on

A ball rolls out of a park and into the road while someone's driving. In Japanese driver's ed, this is a classic textbook scenario for a concept called "kamoshirenai unten" (*"might-happen" driving*) — the practice of assuming the worst-case outcome could happen at any moment, as opposed to "darou unten" (*"probably-won't" driving*), where you assume nothing bad will occur unless you see it directly. A rolling ball is the poster-child example: it means a kid chasing it might be right behind.

One driver spotted the ball, recognized the setup, and slowed down before anything happened. Then, exactly as the textbooks warn, a child ran out after it. The post recounting this near-perfect real-life save resonated widely, and other drivers and parents jumped in with their own stories of close calls, near misses, and the specific dread of almost hitting a kid over a stray ball or a runaway hat.

Comments

Today while I was driving, a ball rolled out of a park, and I thought “oh, this is the textbook case for defensive driving!!” so I slowed down, and sure enough a kid came running out right after. Such a rush.
今日は運転中に公園からボールが転がってきて あ、これはかもしれない運転の典型的なあれだ!! と思って徐行したら子どもがちゃんと飛び出してきて すっごい脳汁出た
Respect for driving safely…
安全運転出来てエラい…
Didn’t know this happened outside of Shinken Zemi (a Japanese home-study service famous for ads where the exact question on a kid’s real exam matches one they’d just studied — shorthand for “the thing you learned in theory actually happened”).
進研ゼミ以外であるんだ
Probably on the same level of real-world usefulness as “This is a pen” (a famously useless stock phrase from Japanese English textbooks, i.e. something you’re taught but never actually need) (;^ω^)
多分 「This is a pen」 の実用並み(;^ω^)
The kid: “the car will probably stop for me.”
子供「車が止まってくれるだろう」
A life saved by something being too much of a cliché.
テンプレすぎて救われる命
That’s a godly dodge! As a driver, I’d love to be able to make that kind of read every time.
神回避ですね! 運転手たるものこういう予測が常にできるようになりたいものです
Great job paying off the setup (in storytelling slang, a “flag” is a hint that all but guarantees what happens next).
フラグ回収がちゃんとされてて素晴らしい
So it really does happen… that kind of textbook development…
ほんとにあるんですね…そんなお約束な展開が…
There are fewer parks these days where you’re even allowed to play ball, so this might become an urban legend eventually.
最近じゃボール遊びできる公園も減ったし そのうち都市伝説になるんでしょうな
Anyone else run into this while driving? 🙋 I have too!
運転中にこのイベントに遭遇した事ある人🙋 自分もあります!
A piece of paper blew away in the wind and a kid ran out chasing it — turned out the “paper” was a bill. Yeah, you’d chase that too;
紙切れが風に飛ばされてそれを追いかける子どもが飛び出してきたけど、その紙切れはお札だった; 飛び出すよねえ;
The other day I was driving near my place and a kid — maybe early elementary age — came flying out of an apartment entrance, and I nearly hit them. It was a narrow road so I wasn’t going fast and managed to stop, but it really shook me up, and my grocery bags went flying everywhere.
先日近所を車で走ってるとマンション入り口から勢いよく小学低学年?くらいの子が飛び出してきて危うく跳ねるところだった。狭い道でスピード出てなかったから止まれたけどホント身が縮んだし買い物袋の中身散乱して大変だった。
Scary… glad everyone was okay. I was on the pedestrian side once, on a road with no guardrail separating it from traffic, and I pulled back a kid who was trying to catch their hat after it blew into the road. Lucky the cars were keeping some distance too…
怖いですね…無事でよかった。 私は歩道にいた側ですが、車道との間にガードレールなど何も無い道で、風に飛ばされ車道に出た帽子をキャッチしようとした子どもを引き戻した事があります。 車も少し離れて走ってくれていたのでよかった。。
As a parent whose kid did this back before preschool age, I genuinely wanted to get on my knees and apologize to the driver… To whoever stopped for us that day, thank you so much!! I was chasing after them, but I just couldn’t keep up with a kid’s legs…
子供が未就園児時代にやった事がある保護者としては、本当に運転手さんに土下座したい気持ちだった・・・ あの時止まってくれた人、本当にありがとうございます!! 追いかけたんだけど、子供の足に追いつけなかったのよ・・・
The scary part is your brain releases that same rush even if you do hit them.
弾いても脳汁出るから怖い
Not every driver has this kind of danger-sensing instinct though.
こーゆー危機予知能力があるドライバーばかりじゃないからな
Funny enough, as a kid I once chased a ball out of a park and right before I ran into the road I thought “wait, isn’t this the classic dangerous setup?” and stopped myself — and the car had already stopped for me too.
ワイ逆に子供の頃、公園からボール追いかけて道路に飛び出す直前で「あれ、これ典型的な危ないやつじゃね?」とストップしたら、車が止まってくれていた
A ball rolling out is basically a done deal at that point. A real pro slows down the moment they see well-kept grass and thinks, “this is maintained — a park? a preschool?”
ボールが出たなんてもう決定してるじゃないですか。通は草見たら「手入れがされている。公園か?幼稚園か?」で減速体制に入る。

My take

It goes without saying that drivers need to stay alert, but maybe the real issue is that everyone sharing the road just doesn't share the same sense of danger.
