I’m guilty of this to varying degrees. All motorcyclists and any bicyclists that are doing it as a hobby. I get it for cars where, in my entire continent, they are pretty much a requirement. You have to have a car (let’s not do a car-free digression right now).

But motorcycling? Or trail biking? Those are electives. I have bias because I’m mechanical and the people I get along with tend to also be mechanical. Both hobbies are ones where mechanical issues are frequent enough that you’d rather not be stranded for something basic - or, at least, that’s my thought process. With a bicycle, there’s not a whole lot to it (to me) so why not have the pocket multi tool that could disassemble the whole bike and why not know how to use it? With motorcycles, they have some flukes and tows are so tricky/pricey that I’d like to exhaust all my diagnostic options first. I guess I do have the same view on car drivers as well, but in limited ways. Namely, how to change a flat. I charitably change about 3 a year randomly on the road.

That’s my thought process. It matches my initial facial expression. I try to not put it out verbally though and just help if I can.
