Tbh, the cyclist shouldn’t have been on the phone.
Not sensible but there’s no way you could say it contributed. He wasn’t wobbling, out of lane, or doing anything else that resulted in him getting hit. If I’m on the phone whilst driving and I get caught in the crossfire of a drive by shooting are you going to say it’s my fault for being on the phone?
Perhaps if we ban cyclists at busy times. Or it could be voluntary.
Assume this is ironic. Given that cyclists now form the largest single user group on some roads in rush hour it would be more effective to ban motor vehicles ‘at busy times’….
In the morning peak (7-10am), up to 64 per cent of vehicles on some main roads are now bicycles. Cycles make up almost half of all northbound traffic crossing Waterloo, Blackfriars and London Bridges, and 62 per cent of all northbound traffic crossing Southwark bridge in the morning peak are cyclists. They are the largest single type of vehicle on each of these bridges, outnumbering cars in each case.

At the top ten main roads for cycle traffic bikes represent 42 per cent of the traffic in the morning peak but take up as little as 12 per cent of the road space
