I took my dad shopping today, like I do every Saturday, he’s 86 and almost blind. He’s always loved his cars and driving, drove all around Australia. We talked about the new driverless cars being introduced. His face lit up with the possibility of owning his own car again and freedom for the elderly. I later imagined a constant stream of sightseers clogging the arteries during peak hour; and missing grandparents found four months later in the Gibson Desert with an empty fuel tank. But worst of all, I’d miss out on taking my dad shopping.
