It's a joke–a riff on a Parks and Recs meme making fun of Venezuela at the time. We don't jail aircraft engineers when they make a mistake because just sending people to jail doesn't work as well as encouraging them to co-operate ex post facto so the root cause can be identified.
Poe's law strikes again. Of course nobody thinks crashing prod should result in jail, or most software engineers would have spent some time behind bars by now. However it's entirely unclear whether @CountHackulus meant "of course autonomous car engineers should be jailed, just as if an engineer signed off on faulty plans" (which to be fair, also happens), or is just repeating my joke with bridges.
You'd be surprised at how many intelligent people really do want this.
