Except that's a really bad analogy. It's more like you set up guard rails, and every time your vehicle hits a guard rail you change the algorithm it uses for navigation until it can do a whole run without hitting a guard rail.
I've experienced myself how the code quality of proper TDD code can be amazing. However it needs someone to still actually care about what they're doing. So it doesn't help with idiots.
It is not be a good analogy for TDD as properly practiced, but it seems to be very fitting for the situation described at the top of this thread, and that is far from being a unique case.
I don't think it's a generous analogy, but it's poking fun at being test DRIVEN, rather than driver driven. I think he'd agree with you that it's the thinking and navigating and "actually caring about what they're doing" that matters. Tests are a tool to aid that. Tests don't sit in the driver's seat.
Yeah. To me "test driven" really means that I write code under the constraints that it has to make writing my tests sensible and easy. This turns out to improve design in a large number of cases. There are lots of other constraints you can use that tend to improve design as well (method size, parameter list size, number of object attributes, etc are other well known ones). But "test driven" is a nice catch phrase.

The response to every analogy ever made on the internet. Can we stop using them yet?
Spot on: "Analogies: Analogies are good tools for explaining a concept to someone for the first time. But because analogies are imperfect they are the worst way to persuade. All discussions that involve analogies devolve into arguments about the quality of the analogy, not the underlying situation." - Scott Adams, creator of Dilbert (I know he's quite controversial since the election, but he's on point here) in https://blog.dilbert.com/2016/12/21/how-to-be-unpersuasive/
Scott Adams has been quite controversial long before the elections, ever since he got busted as a sock puppet "plannedchaos," posing as his own biggest fan, praising himself as a certified genius, and calling people who disagreed with him idiots, etc. Not to mention his mid to late '90s blog posts about women.
But at least he wasn't using analogies, huh?

>Dilbert creator Scott Adams came to our attention last month for the first time since the mid to late '90s when a blog post surfaced where he said, among other things, that women are "treated differently by society for exactly the same reason that children and the mentally handicapped are treated differently. It's just easier this way for everyone."
>Now, he's managed to provoke yet another internet maelstorm of derision by popping up on message boards to harangue his critics and defend himself. That's not news in and of itself, but what really makes it special is how he's doing it: by leaving comments on Metafilter and Reddit under the pseudonym PlannedChaos where he speaks about himself in the third person and attacks his critics while pretending that he is not Scott Adams, but rather just a big, big fan of the cartoonist.

Hmm, that sounds an awful lot like another analogy to me, actually... Oops!
So maybe Scott Adams isn't the most un-hypocritical guy to quote about the problems of analogies.
