Actually I have.
I would say 90% of people who claim they don't know how to change a wheel,
- have never tried,
- got someone else to do it because they are convinced they don't know how without even thinking about it,
- too darned lazy to try.
1. If someone has never tried, they don't know how to do it.
2. If someone doesn't know how without thinking about it, they don't know how to do it.
3. If they are too lazy to try, they have never tied. Se #1.
So those 90% who claim they don't know how to change a wheel
don't actually know how to change a wheel.
Yes, maybe I am being pedantic (I am) but I am OK with that.
So, you say how hard can it be to work it out? So assuming the person can access the bolts, and has indeed looked at the wrench and determined which end to use, how do they
know which way to attempt to turn the bolt or nut?
Go back a step, how do they
know they have to un-tighten the bolt a bit before jacking?
Go back a step, how to they
know how to use those pathetic little jacks in moderate safety. I know, the user manual has all of that stuff in it, but not all of those are still in the car.
The fact is changing a wheel is hard if you've never done it or had to think about it before. There is a lot of stuff that comes naturally to many of us but not everyone. Some people can work it out, some cannot. For some it is a confidence thing, they don't have the confidence to do something so critical to their car. And lets face it, changing a wheel is pretty critical to the car, so that is understandable.
Do not judge everyone by your own standards or abilities. Everyone has different backgrounds, different skills and differing levels of practical/logical ability.
