Oh wow, so it’s actually a thing. What kinds of responses do you get from drivers when you talk to them afterwards?

Thanks also for mentioning the term ‘punishment pass’, googling this led me to some interesting blog posts.

You also might find the acronym MGIF (must get in front) to be interesting. I think it's mostly used by British cyclists.

If my memory serves, the responses range wildly. On one end you have completely reasonable and sincere sounding apologies that they accidentally passed me dangerously. Whether or not these were accidents, I don't know. On the other end you have the typical rants against cyclists. In the middle I might help convince bad drivers to treat cyclists nicer.

One time a driver I was speaking to seemed apologetic and some random pedestrian started screaming at me about how I shouldn't be telling drivers what to do. That guy was nuts.

I didn’t know the MGIF acronym although the attitude is something I pretty much take for granted. If I’m on a narrow road with a car behind me, I mostly expect the driver will try to squeeze past me even though they won’t be significantly faster.

Oof, that's where defensive cycling is important. Whenever I come up to a spot where a car and a bike cannot fit side by side (with safe clearance), I take the lane.

That's awesome you talk to them. I imagine most people yell or do something dangerous because they think they'll never have to face you afterwards.
