The #IllRideWithYou hashtag was begun by Tessa Kum, a TV content editor and writer who lives in Sydney.
She told BuzzFeed News her "heart broke" after she saw this story:
It is hard to feel hope when you feel helpless. #illridewithyou is a small act, but might be important for someone one day. My thoughts are with those involved, who will be affected for so long to come, and those uninvolved, who are being blamed none the less.
For those of us watching; we live in this world. We aren't bystanders. We aren't helpless.
