The Sunday Mirror hit the road with a cycling activist who has snared a string of stars – and found a horde of drivers flouting the law.
We saw scores on phones, with some emailing, messaging and even watching TikTok videos.
Footage was captured by our guide Mike van Erp, a road safety campaigner whose own father was killed by a drink-driver. Since 2006, Mike has reported 1,000 drivers including Guy Ritchie and Chris Eubank.
