How do you PR the future? That's the question David Yelland and Simon Lewis are wrestling with this week. As Uber says it's 'ready to go' with driverless cabs, can the British public be persuaded to jump in?

How do you sell a vision?

Also, in the extended edition on BBC Sounds, they look at Gary Lineker's departure from the BBC and the PR rules around staying silent or speaking out. And when is a gift not just a gift? Possibly when it's a $400m plane. David and Simon pull back the covers on the world of freebies.
