"Because of the slower traffic pedestrians take more risks venturing into the road"
The interesting part is that the idea that pedestrians don't belong on the road is relatively recent, pushed by motor vehicle makers (The idea of 'jaywalking' bring a crime in the USA being one very specific example)
This is a movement for pedestrians to take the road BACK - and quite frankly it's about time.
If pedestrians start walking confidently into the road despite the presence of cars then city traffic will revert to the old days where the vehicles would simply slowly roll through. They don't need to stop unless there's a wall of bodies in front of them or someone lays down in front of the car.
With London traffic averageing less than 10mph (probably less than 5mph in the core), this won't produce much in the way of slowdown - and with robot cars meaning that the desirability of personally-owned vehicles being lowered (insurance costs of owning, vs lower labour costs for being driven meaning that in most cases it will be more expensive to own than hire), the number of vehicles on the road (AND parked on the sides - a parked car isn't earning revenue) is likely to plummet, making streets far less crowded and congested than they currently are.
