My eldest child has reached one of the most important milestones in the life of someone growing up away from functional public transport – he’s learning to drive. This is, of course, terrifying. From his tendency to run before he can walk, to his complete inability to avoid denting everything he has ever owned, there’s so much that can go wrong. Even before he has passed his test, I’ve faced perhaps the most horrifying part of the whole process – the cost. It has reinforced how impossible life’s milestones will be for the next generation to afford alone. Either I’ll have to step in, or my kids will end up with far more limited options than I had at the same age.
