I am not at all an expert on bikes, I've always been told that you shouldn't use WD-40 on bike chains, but I've never really dug into the details on that. And not for nothing my own bike is a belt drive so it's not even relevant to me.
Every time WD-40 comes up you're going to get a whole lot of regurgitated, half-right information.
A lot of people are going to tell you that WD-40 isn't a lubricant. That's wrong. It's not a particularly good lubricant for most applications (I think I've heard that it actually makes a pretty good cutting oil for certain machining tasks in certain metals) and there's usually going to be a better, more effective, longer-lasting lubricant you should be using instead, but it does, in fact, provide some lubrication. Rub a little bit of it between your fingers, feels slick and oily doesn't it? That's lubrication.
People will bang on about it being a water displacer. Know what else displaces water? Oil. Grease. Pretty much anything else that doesn't mix with water.
As for being a degreaser, like dissolves like. Non-polar chemicals like oil and grease are generally miscible in other non-polar substances, so a lighter oil will help to thin out thicker grease so that they're easier to clean away.
I believe it also contains some other more volatile solvents that also help with degreasing. This is part of how it does it's water-displacing/rust-preventive thing. The oil is further thinned out with those solvents so it can coat the surface better and those solvents then evaporate off leaving a thin film of slightly thicker (though still pretty light) oil.
And being so thin and light, it makes an OK penetrating oil so that it can soak into the tiny gaps around seized-up bolts and such to lubricate them, and the solvents help break up any other dirt and grime in there to help break it loose.
Again, not a bike mechanic, take my advice for what it's worth (not much) but WD-40 is probably just too light of a lubricant to use for long. In a pinch if I had a bike with a really rusted, gummed-up chain that I only needed to ride maybe a couple blocks to get home (and just walking it on throwing it in a car wasn't an option for some reason) I personally wouldn't hesitate to douse it in WD-40 and hope for the best until I get it home to properly clean and lube it.
My general DIY philosophy for WD-40 is "this will get things moving right now so that I can diagnose the problem or finish the immediate task at hand, then I need to run out and get the right oil/grease to do things properly.
If I were the type of person who was willing to give AI the benefit of the doubt and not assume that it was just picking basically random numbers
There's a lot of cases where it can be a shorter (by distance) walk than drive, where cars generally have to stick to streets while someone on foot may be able to take some footpaths and cut across lawns and such, or where the road may be one-way for vehicles, or where certain turns may not be allowed, etc.
I have a few intersections near my father in laws house in NJ in mind, where you can just cross the street on foot, but making the same trip in a car might mean driving half a mile down the road, turning around at a jug handle and driving back to where you started on the other side of the street.
And I wouldn't be totally surprised if that's the case for enough situations in the training data where someone debated walking or driving that the AI assumed that it's a rule that it will always be further by car than on foot.
That's still a dumbass assumption, but I'd at least get it.
And I'm pretty sure it's much more likely that it's just making up numbers out of nothing.
