Up until that point, our family had our own space to spread out. Money was tight, so there was no television set, but we owned a turntable on which my dad’s records played constantly. Mostly, it played Bob Dylan. Tracks from The Basement Tapes and Desire became an important part of our new life. My brother and I, aged 8 and 10， climbed trees, built hideaways and learned the words of Clothes Line Saga. We would chant over and over, lost in our own joy. It was January when my dad left us forever because of the cancer. He was 36 going on 37 then, the same age as Dylan. Afterwards, our laughter disappeared, but we kept on playing the records, which became our only ritual of remembrance. The two men became so intertwined in my head, I struggled to tell them apart.

A retirement munity in San Jose, Calif. , which has been transformed by a small fleet of driverless taxis, shows the potential of selfdriving cars to transform people’s lives. Built by a tech startup called Voyage, the modified Ford Fusions are currently limited to a twomile road, but residents are already having the benefits of these autonomous vehicles, which allow them to participate in social activities they would otherwise be unable to enjoy simply because they could not get to them.
