Anecdotally, every car I've been in where the driver talks about engine braking is rode hard and put up wet. Humans seem pretty bad at downshifting/engine braking outside of vehicles designed for that purpose like big rigs. Cars have much fewer gears so it's harder to align the downshift.

Of course there's little use in having this conversation since we all think ourselves above average drivers. I've had acquaintances reply "I don't even need a clutch I can shift so smooth!" (Do not attempt.)
