Only skimmed thread so apologies if I missed or repeat anything.
Have two examples of this in RL. First, a friend whose husband is capable of driving, not scared or anything (happy to go out on his scooter, which is scarier to me than being in a car), but who never manages to prioritise getting a test booked and therefore can't share the driving - i.e. giving lifts to their two DC (4 and 8) who do a lot of activities. Both work fulltime. They do share transport responsibilities to a degree but the extra time that public transport takes means my friend often ends up doing more transporting than her DH as it's just quicker for her to drive and some of the activities their DC do wouldn't be possible if public transport was the only option. Both sets of GPs are also heavily involved in lift-giving, even though they live 40min/1hr away, which they freely admit wouldn't be the case if the H could drive. It seems unfair to me, especially as it's not just his wife who is affected, but they do seem to make it work by sharing other activities (e.g. housework) more evenly than some couples (e.g. DH and I!).
Second is my BIL. He has a bike license and is forever going on about being just about to do his car test - he's been saying this for about eight years so far, so not expecting it to happen soon. He can afford it, and can also drive - his girlfriend takes him out sometimes in her car so he can keep his hand in. I strongly suspect that a part of the reason he hasn't taken his test is because then he would have to drive and not rely on his girlfriend, us, or his mum for lifts. It's not my business, but it does get right up my nose when we see them and he is always having a drink and joking that whoever is giving him a lift on this occasion can't drink, ha ha, so he'll have an extra one for them (usually paid for by someone else too but that's another rant).
So I suppose my point is just that if it works for you and your family, whatever reason you have for not driving, then it's fine to be a non-driver, but if you're taking the piss, that is bloody annoying and unfair and I'm not going to give you lifts any more, 'dear' BIL. Rant over
