Your car repeatedly doesn't start so instead of taking it to the shop, you... write a letter to the CEO of Pontiac who not only actually reads the letter but also personally dispatches an engineer to waste a week going out for ice cream? And Pontiacs have a known vapor lock design flaw that only you, the letter writer, are experiencing? And you've only experienced it on your ice cream runs? And you've never got the vanilla ice cream but took a little extra long so the vapor lock dissipated and disproved your cute theory about vanilla ice cream?
Seriously, this is one of those dumbass stories that come from your boomer relatives with the subject line "fwd: fwd: fwd: fwd: fwd: fwd: fwd: fwd: re: fwd: fwd: fwd: fwd: fwd: fwd: vanilla ice cream"
Nobody actually believes this story is true, right?
While I appreciate your point, I think anyone who has spent sufficient time troubleshooting complex systems has dealt with similar types of problems, and can grasp the _spirit_ of the story.
In fact, I'd argue the quaint style of the story does geeks a favor: if it's appealing to normies, maybe they'll appreciate us technical folks' perspective a little more.
actually the story is detrimental to helping people understand how technical systems and troubleshooting work, because it's so poorly invented.
lots of people, both technical professionals, and non-engineers who are observant and have an appropriate level of belief in causality, troubleshoot transient failures like this all the time. a difference in the amount of time between shutting down the engine and starting it up is one of the first things that someone like this would test, or control for. it's beyond implausible that the second time the guy got vanilla (after riding along for 4 trips, two long and two short), the engineer didn't raise the question of how long he was in the store.
people troubleshoot things like this by being able to separate causes which are plausible, although unlikely and surprising, from things which aren't remotely plausible. the 500-mile email story and the stories above about sunlight interfering with sensors demonstrate this.
if you're the sort of person who believes that the type of ice cream you get might affecting your car's ignition - the type of person who buys ice cream often but never thinks about how long the errand takes, you simply never get the point of being able to make a pattern between those two things. the second time your car doesn't start, you blame it on the scratch-off lottery ticket you won $2 on which used up your supply of luck for the day. the third time, you conclude that the car ignition knew you were late and likes to choose its failures to cause maximum annoyance. and the fourth time, you realize that your mother-in-law gave your car the evil eye that morning.
the story as told, especially when presented as a real parable about engineering rather than an amusing myth, is frankly insulting to the other type of person. the untrained, not necessarily educated person who cares about machines and believes in material reality. the person who starts checking their watch each time they go to the store and a couple of weeks later is telling their mechanic friend "if it's more than 3 minutes or so, it's fine. but if you try and start it before 2 minutes, then you have to wait another 5 before it's ready to go".
And having a stranger along for the shopping trip doesn't affect the timing more than the extra walk to the back of the store?
And the engineer is sitting in the car on the first night and it "wouldn't start," which signals the end of the episode for the day. Were they stranded? Did the car start after a few tries, which would have given a huge hint about the root cause? Surely the engineer who had reproduced the issue would quickly narrow it down by running diagnoses on the car itself.
But the family dynamics are the most improbable part here. How does the family have this predictable routine and not simply stock up on ice cream? The family has enough kids that the consume a whole $unit of ice cream per day. So with that much chaos in the house, how does the dad justify going out for a drive after dinner when the chaos of family multi-tasking (cleanup, chores, homework, bedtime) is at its peak? "Oh, look. Out of ice cream again. I'll be back in a few!"
Also ridiculously implausible is that the supermarket keeps vanilla ice cream in a completely different location in the store.
Aisle caps commonly feature a product that would ordinarily be found alongside a bunch of closely-related products somewhere else in the store. But I don't think I've ever seen a refrigerated aisle cap.
Obviously, they'd put the most popular flavor way at the back of the store, and the least popular flavors at the front. The store is not in the business of maximizing throughput of customers - quite the opposite, they want customers to spend more time walking and getting lost between shelves, as this maximizes the amount of wares moved.

..nor would the featured product simply be one flavor of ice cream, as opposed to, say, all the Ben & Jerry's.
