You really can't ride like that though. That would mean slowing down to 10mph at every junction with an arriving car. You can take steps to be seen - put yourself in a cars sightlines and watch carefully for signs of not slowing down. But ultimately you are moving at a speed which means if someone absolutely guns it out a junction, or changes lanes without looking, you will be hit. Watching carefully for signs of not being seen reduces the risk, sure. Often to acceptable levels. But it's always there.
