YANBU at ALL
The problem is that if you don't learn, you are really scuppered when you are old.
Working with old laydees in the parish involves cajoling drivers into ferrying them to hospital appointments/social engagements all the frigging time.
The ones who are widowed are in the worst position becuase they relied on their husbands for years and years.
You can't always USE a bus when you are old - can't stand around waiting and can't even get ON the bloody things. And that assumes that you will retire somewhere with decent transport anyway, such as ermm London. If you want to live anywhere rural or abroad then you are jiggered if you can't drive in your final years.
If you want to live to a ripe old age and want ANY sort of independence, then LEARN TO DRIVE. Otherwise, frankly, you will be totally at the mercy of a church community or your family.
