I will have to disagree with the comment about ability to change a wheel there are plenty of perfectly safe and able drivers who for one reason or another are not able to physically change a wheel.I carry a long torque bar for nuts, flat lever to lift the wheel up a inch or so to line up with the studs, next thing I'm buying is a couple of tyre inflating gunk.
I do believe when you cannot change a wheel its time to give up and hand the licence in, do remember its an offense to drive on an underinflated or damaged wheel.
You and I and many others are fortunate that we are still able to do so, but I wouldn't make doing that a prequesite to driving. There are plenty of people on the road who can change a wheel but shouldn't have a licence to drive!
PS. the flat lever .... something some do is get a headless bolt and drop it into the hole to help support the wheel when you are lining it up with the bolt holes.
