Barring situations where an illness or financial circumstances proscribe it aibu to think adults who can't drive are a PITA. People have to constantly go out of their way to collect/drop them off places; arrange plans around the times that suit the non-driver who can't travel solo but has to tag along with you; always be the designated driver who can't have a drink while the non driver happily slurps a third glass of wine etc etc etc
Yes, I have been spending too much time with a non driving sibling over the family Christmas but AIBU to think that a perfectly functioning adult (who is extremely technically minded) in full time paid employment, should bloody well learn to drive.
