Cyclists shaming drivers online, fights over bike lanes, and the politics of pedal power. TV and radio presenter Jeremy Vine posts a video of a car failing to give way to him while he’s riding a penny farthing. Cue angry comments hurling insults and telling him he’d be safer in a car - and sympathetic responses from fellow cyclists. What does the Highway Code actually say about priorities on the roads? What are the stats on cyclists and safety? And how and why has cycling become such a toxic topic? Presenter: Adam Fleming Producers: Simon Maybin, Simon Tulett, Nathan Gower Editor: Richard Vadon
