Is it? He's describing "almost being hit." That's pretty squishy. I think most people who do a lot of walking or biking could come up with 10 "close calls" for some definition of that term.
Yeah, it's a very fuzzy definitions. By HN/Reddit well to do urbanite standards I've probably "almost" been hit dozens of times. By 1970s construction site standards I've probably never had a truly close call.
Nearly 100% of my close calls have been the result of miscommunicated intentions between me and drivers and none of them have been very close. I generally prefer drivers treat me as invisible and do their thing and I time my moves to not interfere with any of that so inattentive drivers don't increase the threat much for me.
