Maybe that other guy had his own "Oh no what have I done" moment when he thought harder about why the person next to him on the bus was being weird about cycle paths.
I like how I know this story didn't happen anywhere close to me since: no one calls them "cycle paths", we hardly have any "bike lanes" anyway, and we definitely don't have any trains to ride while discussing biking.
Now, if this had been a story about guns, trucks, and psychopaths, it would have been very relatable.
